I held a very successful and inexpensive party for my daughter and her 12-year-old friends by doing my own version of the 'Amazing Race'! When sending out invitations, each person was allocated a team colour and asked to wear clothing in that colour. On arrival they were given a back pack containing water bottles, maps of the town (we live in a small town and had all activities within a few blocks of home) dry biscuits to snack on, a list and bag for a scavenger hunt to find things on their travels, a dictionary, sunscreen and their first clue.

I had friends in the area lined up with different tasks to be completed (these included windows to be washed, shooting a set amount of goals at a basketball court, sorting books into alphabetical order, separating peas and corn with chopsticks and many other easy to prepare tasks). Each team had a passport to be stamped when each task was completed and the next clue was handed over at each destination. For the final clue, they had to use the dictionary to work out the coded directions to their final destination - our local swimming pool where they spent a couple of hours playing around before heading back to our place for the party food!

This party really didn't take much to organise once I got into it; just a few friends willing to give up a little time for each task and some imagination. I used items from home to make up the challenges, such as books, jigsaws, basketballs and frozen vegies. It was talked about for weeks afterwards and I used photos from the day to make a photo slide show, which I burnt onto discs for everyone who came!

I'm saving money, time and sanity by serving dinner much earlier – here's how! With three young school children, I was finding they were coming home really hungry from school, eating up and were not hungry at dinner time. This meant I was struggling to find healthy, economical after school snacks and throwing away perfectly good dinners! The solution? I changed our dinner time to 3.30–4pm! They have a healthy, nutritious meal when they're hungry and a small snack such as fruit later in the evening. No wasted dinners, no stressed mummy! I have their dinner ready when they get home and then have more time to help them with homework. They are also helping out more with dishes and so on, which is a great help to me.

Here's a great way to save heaps of money on popcorn.
 
I buy a packet of 200 Home Brand paper bags for about $3.00 from Woolworths and a 500g bag of No Frills popcorn kernels for $1.16 from Franklins. I smear some butter in the bottom of a bag and pour in about 100g of kernels. I then seal off the top of the bag by folding it over twice.
 
I set the microwave to cook on High for about three minutes but I always listen closely because the time it takes the kernels to pop depends on how much I have placed in the bag. When the frequency of the 'pops' slows to about three to five per second, I stop the microwave and let the remaining kernels stop popping before removing the bag from the microwave and adding salt.
 
For a healthier version, I simply cut out the butter and salt. I sometimes add chilli flakes or chicken salt, however, there's lots of room to experiment with a variety of flavours. Each bag of popcorn works out to about $0.25c per serve, a huge saving on the ready-made variety at the supermarket.

If you have an old bookcase that you no longer need, or is a little too unsteady to use as a bookcase you can transform it into a super cheap underbed storage container! All you need is to buy some castors from your local hardware store. Just screw the castors onto the back of the bookcase, lay it down on its back and roll it under the bed. We have one of these in our boys' room for all their toys and it really reduces all the visible clutter. It's lovely to walk in and all you see are their beds!

As a new member, I have saved $150 in my first week, thanks to the $21 Challenge! I thought I was careful with money until I discovered this site and realised how I could further improve my spending habits. I decided to give the $21 Challenge a go and it is now Thursday and I haven't been to the shops yet!

I have become a problem solver due to the fact that I must use what is in the fridge/freezer and pantry. I nearly buckled when my four year old wanted 'pink milk' and I had run out of Nestle Quick but no problem in the end. I found some rose pink food colouring and with just one drop - presto, pink milk! It does take some preparation because you are cooking from scratch but it is all worth it when your family tells you that the dinner you made tonight was the best, and is there any more?

My other dilemma was to use the three zucchinis in the crisper, so I made them into a slice. It was so easy to make and I had every ingredient on hand without even trying!

Zucchini Slice (serves 4-6)

3 zucchini (grated)
1 onion (grated)
1 potato (grated)
4 slices of ham/bacon (chopped)
1 cup of cheese (grated)
6 tablespoons flour (plain)
3 eggs
salt/pepper

Put all ingredients into a big bowl and mix really well. Pour into a quiche dish and cook in the oven for one hour at 160C. If you are vegetarian, simply leave out the ham. Simple, delicious and super cheap!

Skint but stylish. That's how I like to think of my lifestyle, because it is such fun to live on the smell of an oily rag without anyone else knowing! Eighteen months ago, although in recovery from depression, I found myself many thousands of dollars in debt and with several accounts having been sent to collection agencies. I was also 31kg overweight and at risk of cardiovascular disease and Type 2 diabetes. The excess weight (not to mention the stress!) was also making my arthritis worse. I was no longer able to work in my former profession and, as I was in my early sixties, I wasn't able to find other work and was on Centrelink (Social Security) benefits. I have since been transferred to the Age Pension. I knew I had to make some drastic changes, and pretty darn quickly too! I had just a few things going for me:

• My Visa card was a debit, not credit, card.

• My account was with a credit union, rather than a bank, and fees are much less.

• I was knowledgeable about nutrition.

• I was willing to face unpalatable facts about myself and make lifestyle changes.

With this small armoury, I prepared to do battle! The first thing I did was to sit down with all the paperwork, and list all the accounts, personal loans and the total. I nearly had a heart attack right there and then, but with the information, I was able to draw up a projected payments schedule. I contacted all the collection agencies and told them how much I proposed to pay each fortnight until all were paid. I did the same with private lenders. Nobody turned my proposal down; it really is true that, if you get in contact and show willingness, most lenders will give you time to pay. They would rather have their money than you in jail!

Step 2 was to organise payment of my electricity account by direct debit from my pension - what you never have, you never miss. Once the phone bill was paid off and reconnected, I did the same with that too. In all, my debt reduction program was going to be about $200 per fortnight, or roughly 34% of my pension and Centrelink allowances. Since my rent costs another 34%, the remaining 32% had to stretch to cover food, cleaning materials, clothing, pharmacy costs over the pharmacy allowance, fares for trips outside walking distance, presents, postage, life insurance and credit union fees (direct debit from my credit union account), occasional small charitable donations and the occasional small treat.

Step 3 was to go on to a sensible eating program (not a fad diet) that would help me to lose weight, bring my blood glucose and serum cholesterol levels into the normal range. A low GI, high carbohydrate, moderate protein, low-fat pattern fitted the bill in all respects. The challenge was: could I do it on $50-$75 per fortnight? The answer is yes! I make my own wholemeal bread, soups, skim milk yoghurt and lots of interesting dishes from many countries, based on grains and vegetable proteins, and stock up on tinned oily fish for essential fatty acids when on special. I have red meat and poultry only once or twice a fortnight and the rest of the time my proteins are derived from legumes, eggs and low-fat cheeses. It's just as well that I like oats! I drink two litres of water a day and make my own herbal teas from homegrown herbs. I don't buy soft drinks and buy leaf tea rather than tea bags, as it's better value per unit serving. I find whole fruit better all round than juice as a rule.

Step 4 was to get mobile! I walk, because I can't afford gym membership, and walking can be done by those who can't jog. Being out in the open air blows away the blues too. Having won a free pedometer, I wear it and try to reach 10,000 paces a day. I also started a vegetable garden and this saves me money where it counts, on vegetables, as well as being another source of fresh air and exercise.

Is it working? Is it what! In the last financial year I paid off $5000 in debts on the pension alone, and am on track to achieve the same amount this financial year. I lost 13kg in the same period - a nice, sustainable rate. My blood glucose level is normal, my serum cholesterol almost so, although because of familial hypercholesteraemia, I need some medication to help with that. I am continuing to lose weight slowly but surely and have much more endurance and less pain. My GP is nearly as stoked as I am. I take care of my clothes, believing that 'well-pressed is well-dressed', so my appearance doesn't give me away either. Occasionally I earn a little money from magazine contributions and this usually goes towards seeds or something else for the garden, but occasionally I restock the pantry with staples. I make my own cleaning products with such simple substances as vinegar, bi-carb of soda, washing soda crystals, soap scraps, eucalyptus oil and - wait for it - Worcestershire sauce (cleans brass and copper a treat, and one nearly always has it handy). I turn my appliances (apart from the fridge) off at the wall when not in use and have noticed a difference in my power usage. All my incandescent light bulbs have been replaced with long-life fluorescent ones, and by crafty use of acrylic-lined curtains I keep my house cooler in summer and warmer in winter. I pile on the clothing layers in winter and wear cool clothing in summer. If I'm watching TV in the winter, I cover my legs with a woollen rug and put on another cardigan if necessary, rather than turn up the heater.

Because I can't afford much for presents, I give of myself. A nice present is a 'book of vouchers', made attractively and containing such redeemable coupons as: 'This voucher is good for two hours' ironing... or an evening's baby-sitting... or... whatever!' Very few people say no to home-made goodies either. It makes me feel truly wealthy to give someone a loaf of bread still warm and fragrant from the oven, or a jar of chutney.

About a year ago my husband and I were having lunch at a seaside cafe when we noticed the people next to us paying their bill with $5 notes. We found out that they were on a trip around Australia and every time they were given a $5 note, they saved it and used it toward their food bill.

Thinking this was much better than saving $2 coins, I started doing the same. As soon as I receive a $5 note in my change, I pop it into my purse and then put it in a money box when I get home. I keep track of how much is in the box by writing the amount in my diary; when I get to $500 I empty the money box, take it to the bank and put the money into a term deposit for a rainy day.

So far I have saved $1435! I never miss the money and most times I go shopping I come home with at least one $5 note!

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.
