I came up with a great low cost, low stress way to feed the crowds at my son's 21st birthday party. With the weather being chillier, the food needed to be warming and more robust than usual. I came up with the idea of a crockpot party! I am borrowing family members' and friends' crockpots and am filling them in the morning with different dishes, then I can 'forget' about them until the evening! When it's time for everyone to eat, I can then just plug them all into a power board and put them on the table. This is a triple whammy saver for me! It saves time as I don't have to spend all day in the kitchen and can get other things ready for the party instead. It saves money as I can use cheaper cuts of meat to achieve tender dishes and - as I don't have to use serving dishes, it even saves on washing up!

My husband and I have began saving up to $30 per week on our grocery bill since we invented 'Grandma's Day!' When we go to the supermarket we ask ourselves, 'would Grandma have been able to buy this item in her day 60+ years ago?' If the answer is no, then we decide we don't need to buy it either! This saves us money on a whole range of items such as fancy dips, designer coffees and biscuits. We used to pay over $3 for a pack of 10 biscuits, now I can make 12 biscuits for around $1. Using plain yoghurt as a base we are even making our own dips; there are so many websites with great dip ideas. Now we are saving valuable money and our waistlines too!

I have found a low-cost wedding gift that will last throughout any marriage. While it does not cost much, each part of the gift has meaning and it is great to give a close family member or friend. You will need to put together a nice bunch of candles, in pairs of the following colours: white, green, dark blue, pink, cream, red, purple, light blue and silver.

Wrap the candles up with a ribbon or put them in a decorative box or basket, with the following poem attached (author unknown):

A basket of candles that come in a pair
In all different colours, for you two to share
The white ones burn first
They are wrapped in white lace
To celebrate your first married night
In your new chosen place.
The green pair is taller, and also much thinner
Burn with the first company you have over for dinner
The dark blue candles are for after your first fight
Use them to burn while making up all night
Pink candles set the mood and pave the way
For your first married Valentine's Day
Now, when your first year of marriage is through
the cream anniversary pair will light for you two.
Red candles aflame, both your futures are bright
Celebrate promotions you've worked toward with all of your might.
By this time we hope, maybe, just maybe
You can light the purple ones, on the birth of your baby.
And just when you thought you'd put these away
Take the light blue ones out for your fifth anniversary day.
Now just one more pair left for the big 25
The anniversary pair that will keep your love alive.
Congratulations Bride and Groom (insert name here)
On the start of your forever
May the two of you always be happy together
And burn these candles
Just the way we said
But please don't forget - blow them out before bed!

This all-natural home-made mosquito repellent costs around $3.00 for a small spray bottle and is kind to your skin and the environment. Mix 50ml of sweet almond oil, 10ml of dettol, 10ml of citronella oil and 10ml of eucalyptus oil in a spray bottle and shake well. We have been using this recipe successfully all summer with no bites and no staining on our clothes.

School holidays are more affordable with the help of the $21 Challenge! Money seems to slip away so effortlessly while out having fun with my teenage kids. Budgeting is something I am trying to teach them about but it is hard to make it relevant sometimes. Then I had a great idea that would make them pro-active with the weekly budget over the holidays, without me being a 'budget nag'.

It is the $21 Challenge week, with a twist. THEY have to go and log all the food in the freezer and pantry, and make up the meal plan for the week. Then all the money THEY save us for the week can go towards some guilt-free fun. It's a great incentive and my kids are learning important household skills.

I saved the price of an expensive handbag organiser by using three $2 pencil cases instead. I have two handbags that I swap depending on whether I am working or with the kids, and always found it a pain to transfer essential items like my wallet and make-up and to quickly find what I need in a big bag. Now my colour coded pencil cases make it easy! The green one holds my full make-up, for the days I have to dash off and do make-up on the train. This stays at home when I'm not in a hurry. The black one holds pens, business cards, USB sticks and so on, and the blue one holds lip gloss, band-aids, paracetamol and post it notes. My items are now easy to swap between bags and I don't have to dig around for smaller items. All for $6.00 and a hunt through the bargain bin at Officeworks!

I have come up with a simple yet super effective way of making sure I never waste any more money on clutter! I'm a sucker for buying toys for my children. Consequently I am now drowning in broken toys, clutter and debt. But now when I'm in the department stores and see something on special or think, 'my girls would love that', I open up my bag and get out my deterrent! I look at the photos I have taken of my lounge covered in toys and clutter and remember that not am I only saving money by not buying more, I am also saving the planet - and my sanity! Works every time!

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!
