After reading The $21 Challenge, I thought I would see which other areas of my life I could apply the Challenge to.

First, I opened a separate bank account and now deposit $21 every week before I do anything else with my money. I see this as a type of retirement fund – it will be nice to see the funds in 30 years time!

My next $21 Challenge is to only put $21 worth of petrol in my car each week. I will park my car further away from where I need to go; this will save money and improve my fitness and wellbeing.

When my phone contract ends soon, I am going to challenge myself to spend no more than $21 on pre-paid phone credit each month - now that will be a challenge!

There are so many ways we can implement the $21 Challenge in our lives, thanks to Fiona and Jackie's inspirational book.

At 12 years old, my daughter is already helping our family save money on snacks using her Simple Savings skills! With five children in the house, we do a big shop just once a month and are careful to make our food and treats last until the next shop. Recently we were nearing the end of the month and getting low on food. I arrived home one day to find my daughter baking biscuits. 'They're Doos!' she told me. 'You always said if there was nothing in the cupboard, we had to make do, so I made Doos!'

The name has stuck in our house and now whenever we have 'nothing' in the house for lunch boxes, snacks or afternoon tea, she just makes a batch of 'Doos' using whatever she can find in the pantry to 'make do' with. She is proving to be very inventive with her recipes and is turning out to be a real baker. She'll turn out simple but delicious treats such as honey joys, choc chip biscuits, Anzac biscuits, pikelets and pancakes in no time at all! She really has shown that you can make something from almost anything in the pantry and would be wonderful at the $21 Challenge! Here is the recipe for her latest creation, called 'Sort of Scones!'

1 cup oats
1 cup self raising flour
1/2 cup sugar
125g butter
1 egg
1/4 cup milk

Mix all ingredients together, then roll into balls and place on a greased baking tray. Bake in a moderate oven (around 180C) for 10 minutes.

I couldn't be prouder of my daughter's efforts to help us save money and keep everyone well fed. Whenever we think our parenting has a lot to be desired, it's moments like this which prove we have to be doing something right - good things do rub off too!

Saving $1.00 a day has helped me afford things I would have otherwise struggled to pay for. I started doing this when my sons started at a private school in the city. They would be invited to several birthday parties throughout the year, so to ease the financial burden of gift giving I used my money box. At the end of the year I would use whatever was left to buy school supplies for the following year.

My children have left school now but I still save my $1.00 a day which I use to treat myself to a pedicure, go to a movie or have coffee with friends. It's such a small amount each day that I find it doesn't really affect my household budget, but it always came to my rescue when I needed it, and now affords me my treats.

I am 22 years old and on a low income, but am well on the way to saving for my first house! I developed a simple system that keeps my savings goal at the forefront of my mind and encourages the support of those around me.

I've always found it hard to save, but one day I got a big piece of cardboard and wrote 'My House Deposit' at the top. On the right hand side I cut out images of a house, a kitchen and a loungeroom that I would love to own one day. On the left hand side I drew a giant thermometer and on the side wrote the figures $0 to $40 000 ascending, just like on a real thermometer. Whether or not I need $40 000 is irrelevant; I look at this table every day and whenever I save another $500, I colour in with a red crayon up to the amount on the tally. I use hints from Simple Savings, such as making my own lunch every day and not buying clothes if I don't need them and now whenever I make a purchase I think of my house deposit and how much I want it far more than a coffee or new shoes!

An unexpected bonus of having this chart is that I've found my family and boyfriend have become aware of my goals and I get lots of support along the way. This visualisation technique really does wonders, and most importantly you are making a concrete agreement with yourself and you stop losing sight of your goals. I'm already a quarter of the way to reaching mine!

Making potato wedges at home is much cheaper than buying them frozen from the supermarket. I use my OXO Good Grips apple divider (bought from a kitchen shop) to cut up a 5kg bag of spuds. I give the spuds a wash before cutting them up into eight wedges and one cylindrical wedge (the kids all fight over these ones). After popping them in boiling water for a couple of minutes I put them onto paper towel to dry, then into freezer bags. These are quick, economical and you can vary the seasonings in different bags, and have them on hand in the freezer for a quick snack or side dish.

I came up with a great gift idea last year, which looked sensational without breaking the bank. I wanted to give families items that they really would use and enjoy, and that would not send my spending into overdrive! I created personalised gift baskets.

Each family member has their own personal likes so I decided to work with them. Most of the items were found in the supermarket, so I added them to my weekly shopping. A few dollars extra each week made little difference to my budget but provided excellent gifts for family and friends. For example, my brother likes hot and spicy food so I purchased minced chilli, hot salsa, oil infused with chilli and hot spices and presented them in a basket wrapped in red Cellophane. Two of my sisters-in-law love fragrance and candles so I made up baskets with different candles, incense, drawer liners, pot-pourri and sachets.

Others included:

• Garlic hamper - fresh garlic, minced garlic, garlic salt, garlic oil and a garlic mincer.

• Chocolate hamper - Jarrah chocolate, Cadbury, chocolate sauce, chocolate ice cream topping and chocolate curls.

• A herb bowl with 'boutique' herbs such as bouquet garni, cinammon sticks, oils infused with herbs and herb cook books.

• DVD hamper - a DVD, microwave popcorn, salsa, corn chips and jaffas.

• Gardening hamper - gloves, secateurs, Osmocote, plastic pot, hedge trimmers and Zero.

• Tea lover's hamper - a trivet, tea cup and saucer, UHT mini milks, tea bags, tea leaves and biscuits.

It is easy to pick a loved one's interest and tailor make a hamper/basket to match. Crazy Clints, $2 Shop and The Reject Shop have heaps of baskets and boxes to present your gifts in. Bowls, platters, saucepans and the like are ideal and useful containers for presentation. All it takes is some Cellophane and ribbon and you have a lovely (useful) hamper as a gift. It also works well for new baby gifts. Fill a box/basket with newborn necessities such as baby wipes, powder, nappy sacks, bibs, bottles, bootees, mittens, singlets, bath items and so on and wrap in Cellophane for that professional look. I saved a fortune last Christmas, yet everyone loved and used the gifts they received.

A novel idea to help my Mum save on new ceiling fans has led to some fantastic and unexpected long-term savings! After being quoted a whopping $160 per unit (pensioner rate) to get ceiling fans installed, we took matters into our own hands and placed an advertisement on local notice boards. It read: 'Experienced licensed electrician required to install three ceiling fans. I would like to trade the costs by doing your washing and ironing for one month.’

Within a few days, Mum had received several enquiries and selected a nice, young single guy who needed a 'mother's touch' to some of his clothes - a lot of stain removal and buttons re-sewn. He installed the fans and dropped and picked the clothes up from her place on a weekly basis. To our surprise we learned he also had connections to plumbers and gardeners and she was soon able to have her bathroom wall retiled in exchange for scrubbing out an oven and re-organising a food pantry for a couple that were having a baby soon.

It didn’t stop there! Before long she was taking up hems, sewing on buttons and doing basic mending in exchange for garden maintenance and mowing lawns. These guys are ripping up old items from homes every day with their trades so these days they even search around to find her the cheapest - or even free - items if she needs them, as well as providing an oven door and dials on her heater for free. They often come across things that others could use but end up in the tip instead.

As a pensioner, Mum has time on her hands and is very experienced in household chores but has a limited income. This trade of skills and services means she can now carry out tasks within her ability and has made some fantastic friends. Her place looks amazing and is she even happy to do babysitting for the families. In turn they really appreciate having a cuddly grandmother figure around. She has a new purpose and a whole new social network too - in fact she looks 10 years younger!

Renovations need not cost the earth. We just bought our first home and it had a hideous old kitchen with brown contact, broken stove elements and musty cupboards that had seen better days. We wanted a new kitchen but it was going to cost $4000. It was money we didn't have, so I used my brain instead and renovated our entire kitchen for under $100.

I bought:
Two bottles of oven cleaner at $3.99.
One second hand element from the dump for FREE!
Two tins of paint from Kmart for $17.99 and $36.99
Curtains that were faulty and discounted to $20 for two pairs.

I stripped off all the contact, cleaned the cupboards and painted the inside with flat acrylic paint. They are now white and clean inside. Then I cleaned the oven and fitted the element from the dump. It looks great. Now the oven will do us until we get that mortgage out of the way! I then removed the cupboard doors and gave them a coat of enamel paint. I took the door handles off, cleaned them with oven cleaner and refitted them - they came up like brand new! Finally I hung my bargain curtains and my new fresh, white kitchen looks lovely.

My husband was very impressed. All it took me was two days work and $82.96 of supplies. Best of all,I saved $3900 on a new kitchen.

For an outlay of $65 I purchased chemical-free ingredients to make shampoo, baby bubble bath, moisturiser, hand wash and washing liquid. I made 500ml shampoo, a litre of washing liquid, a litre of hand wash, a litre of beautiful light moisturiser and 500ml baby shampoo and bubble bath. All I added were essential oils and water to the ingredients and I still have enough ingredients to make several more litres of any product.

My next outlay for a further $50 was for packaging; containers and tubes to make shampoos, moisturisers and lip balms for Christmas gifts. I have saved myself a small fortune. There are several good websites offering these products, however, I found 'Aussie Soap Supplies' the best, which offers recipes as well. http://www.aussiesoapsupplies.com.au/

Buying Christmas presents for adult friends and family can be both expensive and stressful, especially when trying to match the perfect present to the person.

So one year I decided to make up small deluxe hampers which contained a mini bottle of sparkling wine, two plastic champagne glasses, chocolates, mixed nuts and home-made shortbread. I purchased the gold wire baskets from the Reject Shop for $2.00 each and the glasses (also from the Reject Shop) were $2.00 each. The mini sparkling wines were purchased from Dan Murphy's and worked out at around $3.50 each when purchased in lots of six. The chocolates were a good quality brand, and individually wrapped, so I bought a large tray and then divided them up (which was cost effective as I only needed around three in each basket). I then purchased a large bag of mixed nuts, which I repackaged into small Cellophane sachets, and I made the shortbread, which worked out to only a few cents each.

The overall cost of each hamper was around $10, including the cost of gold tissue paper (also purchased from the Reject Shop) to line the baskets and ribbon for decorating. I suggest sticking to one colour theme for each hamper, for example, gold covered chocolates, ribbon and baskets or silver baskets and accessories.

It's a good idea to look in places like the Reject Shop or $2 shops as soon as you see Christmas decorations appearing on the shelves. That way you get the best selection and can start putting them together early (except for the shortbread or any home-made foods you choose to include in the hampers). This way you'll have plenty of time closer to Christmas to concentrate on the children's presents!

I saved heaps of money, made something original and had heaps of fun doing it!
