Keep the straws from unwanted drink bottles

If you have a drink bottle with an internal straw, when the bottle cracks, leaks or dies, don't throw the straw out! Remove it from the bottle and keep it in your cutlery drawer for whenever you need a straw, or keep a couple in your bag for use when you're out. I keep three in a little cotton bag in my handbag for when we order a drink that would normally come with a disposable straw (milkshakes, iced coffees, spiders, soft drinks). After use, I just give the straw a quick rinse in the restroom sink, or wrap in a serviette, and give a good wash when I get home. A simple way to reduce waste and help the planet!

Make every cake of soap last twice as long

To make a cake of soap last twice as long, simply paint the top or bottom with some PVA wood glue and let dry. Doing this means only one side of the soap dissolves, enabling the cake to last double the time. I paint the top side of the cakes of soap when we bring them home. Sometimes my granddaughter even glues a pretty picture to the side!

Create a 'roundtuit' fund

I have found a great way to stop impulse buying. I turn the money I would have spent into a 'roundtuit'. A roundtuit is one of those things you always put off and say you will get 'around to it'. Have you always wanted to learn to ride a horse or treat yourself to a massage? Or buy an art print but, because of the expense, have never got around to it? Well, I now put the money I would have spent on impulse buying straight into my roundtuit fund.

Instead of buying that glossy magazine, I look at the price and I put that amount into a special pocket in my wallet. I try and jot down what I nearly bought as well. When the time comes to buy the art print I have always wanted, I can see that it was worth two magazines, a fast food lunch, a shirt on special and a home delivered pizza. I don't feel guilty because the purchase has been funded by my roundtuit fund.

I no longer waste money on stuff I don't really need and I can also see where I am most likely to waste money, which will hopefully protect me from temptation. Most importantly, I'm able to achieve my dreams, almost without realising it. It's a great way to save for what you really want, so isn't it about time you got around to it?

Sometimes we all have to just make do!

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!
