My husband and I have finally found the key to successful saving! The two of us are dreadful savers; while we're good at putting spare change in a jar, we don't know what to do with it once the jar is full! We thought a saving thermometer would be helpful, but wanted something that wouldn't be so obvious when people came over to visit. So we came up with a more subtle brainwave - a jigsaw puzzle!

We bought a jigsaw of what we wanted (a house) and assigned a dollar amount to every piece. Now we 'buy' pieces of the jigsaw puzzle, the money goes in our jar and we bank the money once a month. We even set up challenges for ourselves, such as who 'buys' the most pieces in a month, and we never have to worry about what to buy each other for presents - we buy pieces of the puzzle of course! Once we've completed the puzzle we're going to hang it on the wall - of our new house!

Toilet cleaning, deodorising and water conservation has never been easier.

You can kill three birds with one stone by piercing a few holes through the lid of a bottle of vinegar and putting the bottle in your toilet cistern. The weight of the bottle displaces the water meaning you use less water with each flush. The vinegar will slowly seep out, leaving your loo smelling nice and making cleaning easier. When the bottle is empty, simply refill it with homemade vinegar which is simply half a bottle of cheap white vinegar topped with rainwater. Leave for 24 hours and it will be full strength and ready to use.

Now, if we could only get men to leave the toilet seat down...

This simple bill payment system lets you take a holiday from paying bills at Christmas time.

Every time I receive a bill, I pay $10 more than the amount required. For example, if the monthly phone bill is $50, I pay $60. This has worked really well for me, and come December I am able to stop the phone, internet, power and rates payments. I use this money for Christmas gifts, safe in the knowledge that my bills are covered.

I am saving around $8.00 a week on expensive air fresheners and bug sprays, thanks to a kitchen mishap! After spilling some cloves during Christmas cooking, I boiled them in 250ml of water. The house smelled wonderful! I let them soak for a couple of days, then poured the water into a spray bottle where it became an instant room and cupboard fragrance. I use the spray to wipe all the kitchen cupboards and not only does it keep bugs away, the aroma is delicious whenever I open the cupboard. No more expensive chemical sprays for me!

This super basic mince recipe saves me up to $100 a month on takeaways, thanks to the convenience of having meals already 'half made'.

All you need are:
2kg minced beef
2 cups of red lentils
2 tbsp of vegetable stock powder, or four vegetable stock cubes
1 tsp dried garlic granules
1 dsp dried onion flakes
4 cups of water.

Place all the ingredients into a crockpot and cook on high for two hours, stirring every 30 minutes. It should be thick, aromatic and an unattractive brown colour (don't let this worry you!).

One batch costs just $13 to make and is enough to serve as a base for seven meals for our family (two children and two adults). This saves heaps of money and time too. I usually freeze the mince in margarine tubs, as that seems to be the right amount for one meal for our family.

The meals I made are:

1. Piemaker pies.
   Allow one heaped tablespoon of basic mince per pie. Pour the mince into a small saucepan and add a large spoonful of gravy powder, or a dessertspoon of cornflour and some Vegemite for colour. Heat and stir until thickened. Spoon into pastry cases and cook in the piemaker.

2. Mexican enchiladas.
   I use Mountain Bread or make my own crepes. Lay the bread or crepes in u-shapes in a large baking dish. Mix the mince with an equal amount of tinned or home-made refried beans. Spread the mixture in a sausage shape down the middle of each crepe, fold each side of the crepe over, sprinkle with grated cheese and bake at 180C until the cheese is melted and bubbly. Serve on a bed of rice, topped with natural yoghurt and some salsa.

3. Stuffed capsicums.
   Halve enough capsicums for half or one per person. Spoon the mince straight into the capsicums, top with some mashed potato, pumpkin or sweet potato. Sprinkle with cheese and bake for 40 mins at 180C. Kids love these as the capsicum sweetens when baked.

4. Baked spuds with topping.
   Allow one potato of appropriate size per person. Cook in the microwave according to manufacturer's instructions. Split a cross in the top and pile filling into the opening. Top with natural yoghurt or sour cream and chopped, sauteed bacon. Allow one large tablespoon of filling per potato. Mix the filling with one tin of baked beans and heat in a small saucepan before pouring on to the potatoes.

5. Spring rolls.
   Mix about four tablespoons of mince mixture with a packet of cooked and cooled Two Minute Noodles, some shredded carrot, and 1/2 teaspoon Chinese five spice. Using filo pastry sheets or spring roll wrappers, fold a small handful of filling into each spring roll. Spray liberally with cooking spray and bake at 180C for 20-30 mins.

6. Greek pasta bake (Pastito).
   Heat a container of mince mixture with a 400g tin of peeled tomatoes. Cook enough macaroni for your family and drain well. Mix with the meat mixture and spoon into a large baking dish and top with your favourite white sauce or cheese sauce. Sprinkle on some grated cheese and bake for 40 minutes at 200C.

7. Shepherds pie.
   Add any vegetables of your choice to the mince mixture. Place into a baking dish and top with mashed potato, pumpkin or sweet potato then bake until heated and the potato browns.

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.

I have decided I want a house which I can clean in minutes and I don't want any more energy or money draining clutter that makes it harder to control. The more I have the harder it is to control and the more motivation I need to contain it. 'Less is more' is my new mantra! I am applying this principle to my finances as well - when I buy too much it is such a burden and I don't have the motivation to stay on top of all the bills. Therefore, less is more - more energy, more money and more happiness!

Instead of paying for one expensive doona, and the dry cleaning costs that come with it, buy two or three cheap doonas, pin them together at the corners, and put them into the same doona cover.

Because cheap doonas are thinner, you can wash them one at a time in your washing machine, and you can also adjust the warmth. When the weather starts getting warmer, just take one doona out of the cover and put it away in the cupboard.

I have come up with a low cost way to give a 'get well' gift that is always appreciated! Instead of flowers, I send the patient their favourite treats from the supermarket. In the past I used to send flowers but the cheapest I was able to get was about $80! So I came up with this cheaper alternative.
Now, when someone is sick, I buy around $30 of the patients' favourite foods and magazines online from the Coles or Woolworths websites and have it delivered to my friends and family in hospital. You simply put in their hospital address. You can even add a note to say it is a gift from you!
Delivery is usually free, or a maximum of $5.00. This saves me $50 a time on flowers and people really appreciate the thought and effort I have gone to in getting their favourite treats. It is also a very welcome relief from hospital food!
