Swapping roles with my husband forced him to start budgeting and to learn to take control of our finances!

My husband and I are happily married and are about to celebrate our 50th wedding anniversary, but there was a stage in our lives when we were raising three children and our finances were incredibly stretched, yet he refused to accept it.

One day there was no bacon for his breakfast (he likes bacon every day) and he lost his temper. Rather than get angry back, I wrote him a letter resigning as housekeeper, mother and wife and gave it to his secretary.

He finally agreed to talk and I got him to agree that for one month he would take responsibility for running the house on the budget I had been working on. It wasn't long before he asked 'How on earth do you manage? We need to reassess our finances'.

Since then we have always cooperated when it comes to getting through a tough period.

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...

I can make hundreds of litres of liquid plant food from just $12 worth of Dynamic Lifter pellets! This will buy a 10kg bag. Just add around four handfuls of pellets to a nine litre bucket of water and let steep for a couple of days, mixing occasionally. When you have a nice 'tea', pour a couple of litres of the liquid, into a nine litre watering can, top up with water and give your garden a drink. Repeat until all the 'tea' is gone, then add more water to the residual at the bottom of the bucket and repeat this process. As the mixture gets weaker, you can use on seedlings, vegetables and more delicate plants such as azaleas and gardenias. The 'weak' mixture can be used as a health tonic or sprayed directly onto the foliage of plants (remember not to spray if the weather is over 20 degrees Celsius, as this will burn the foliage). Once you get to the real weak stuff, simply pour the residual under a tree and water in well.

You can also make hundreds of litres of liquid fertiliser from a 10kg bag of Blood and Bone pellets at an initial cost of approxiamtely $1.20 per kilo. Compared to a litre bottle of liquid plant food (such as Seasol) which costs about $10 and will make just over 300 nine litre buckets (going on the manufacturer's average of 30ml per bucket), your bag will make many hundreds of buckets of first grade solution followed by many more second and third grade 'weak' solutions which are ideal for foliar feeding. A huge saving, which will give you enough fertiliser to last you a whole year or more!

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!

I took on the $21 Challenge, and won! However, my husband was a rather grumpy participant; he loved the savings but not the lifestyle during Challenge week. As he goes away regularly, I decided that every night he's not home for dinner would become a $21 Challenge night for the kids and I - all meals must be made from ingredients I already have at home, and I can only use ingredients that have not been allocated for other meals. This saves money and gives me a night off cooking, as my Challenge meals are usually simple affairs, sometimes as easy as pancakes or toasted sandwiches.

The true value of the $21 Challenge became apparent when a friend was recently diagnosed with a severe form of leukaemia. She is a married mother of four boys and is embarking on a long therapeutic journey that will hopefully lead to a full recovery. As a way of helping her family, the parents at our school have banded together to make all their meals for the next three to six months. As they are a large family, with an above average food requirement, I was unsure how I could afford to help feed them each week. Thankfully, my husband was away the week my friend was diagnosed, so the kids and I lived off the $21 Challenge that week and all leftover money was put into making meals to freeze for my friend's family.

We now do the same thing whenever my husband is away – it's a great gift over the Christmas break to know that I can afford to cook and freeze meals for my friend's family, and look after my family at the same time. Thank you.

I wanted to share this excellent method for cleaning your oven.
 
Heat your oven to 250C and place two casserole dishes filled with water on each oven rung. Leave for one hour, ensuring the casserole dishes do not boil dry. Turn oven off, remove dishes and let the oven cool for a few minutes. Remove rungs, then wipe oven clean with a soft cloth. The rungs may need a light rub with a Scotchbrite cloth.
 
The new cloth I used was black in no time but my oven was sparkling clean without the use of chemicals, and only for the cost of heating the oven! An impending visit from the oven repair man motivated me to clean the oven. He commented on how sparkling clean it was – he even wrote down the cleaning instructions!

I make this vegetable pasta sauce for three reasons - it's cheap and healthy and it uses up leftover vegies (cooked and uncooked) so I save three times!

Whenever I serve up a dish of vegies for dinner (usually broccoli, carrots, beans and zucchini in my house) and it isn't all eaten, I put the leftovers in a ziplock bag and throw it in the freezer. Then, when my fresh vegies are starting to get to that 'oh dear' stage, I start cooking!

In a big pot, with a bit of olive oil, I fry onion and garlic and add all the 'oh dear' vegies - sometimes there is a fiddly bit of broccoli that is too small to use in a meal or carrots that are starting to wilt. Other vegies I have added include celery, cauliflower, broad beans, spinach, cabbage and capsicum. I chop and cook all of this - in summer I add fresh tomatoes, in winter I throw in a couple of cans of Home Brand tinned tomatoes. To this I add the frozen leftover vegies, a squeezie stock concentrate or stock cube and some water.

I cook the whole lot until everything is soft, and then I blitz it in a food processor or with a Bamix until it looks like pasta sauce. I then freeze this in meal-size portions and use it for everything - I add it to mince for bolognese, or just use it neat. My kids don't know it's full of vegies - they just think it's another jar of commercial pasta sauce!

For a super, low-cost, personal and heartfelt gift, why not give someone a Happy Bag? All you need is a plastic 'loot bag' such as those given away at children's birthday parties, and fill with the following:

*An eraser - so that you can make your mistakes disappear.

*Five cents - so you can never say that you're broke.

*A marble - in case someone says you've lost yours.

*A rubber band - to stretch yourself beyond your limits.

*A piece of string - to tie yourself together when things fall apart.

*A bear hug (cut out teddy bear picture or motif) - to remind you that someone cares.

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!

If you've just boiled up a pot full of spuds and are about to tip the water down the drain, stop right now! That water is full of nutrients and vitamins and can be used again.
 
Next time you have potato water, you may like to try using it for soups, gravies, stews, as a base for making stock, liquid in baking biscuits, breads or pancakes, or a broth drink! You can even leave it to cool and pour over your garden plants.
 
I have achieved fantastic results since I started to use the potato water in my home-made bread, rolls and buns. It's a great way to get additional nutrients from our foods and a big water saver.
