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.

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.

Over the past four years I have been fighting my way out of debt. I was left with a large amount of debt when my marriage ended and it seemed I would never find a way out, working nights to support myself and five children and trying to reduce the debt in some way. Then, instead of just reading Simple Savings I began implementing as much of it as I could. Along the way I found that things I previously thought were impossible are just every day now!

Two of my children have now left home and are independent and I have three daughters still living with me. I have found new ways to feed them and where once they would have baulked if I offered them home-made soup after school, they now eat it with relish. A home-made frappe was dessert last night and they were happy and satisfied with that. Fruit jellies, home-made scrolls and calzone along with the batch of cake and muffins or bikkies I make are average snacks and lunches. School lunch today was home-made soup with home-made pizza scrolls. It certainly took a while to change their views from believing that everything had to be store bought and chips were the afternoon snack.

I am now debt free and have savings - something I never thought I would have! Bulk toilet paper, bulk washing powder, skim milk powder, and bulk meat buys at a discount butcher and fruit from the growers has saved me a small fortune.

I recently moved in with my partner to his home with the girls and together we have been able to make more and more changes which once would have not been thought possible but with small steps we have cut out television unless it is a special documentary or one of the two shows per week we deem suitable. The girls now play outside or garden, or read and do homework after school instead of being glued to the 'box' and they haven't asked to play Nintendo for weeks now. Water or weak cordial is the staple drink, with the occasional juice for a treat.

I am now a stay at home mum and as long as I can feed this family, pay for petrol in my car and keep the girls clothed for under $500 per fortnight it will stay that way. I am working hard to make sure these dreams come true.

In reality there is no sacrifice - you just need to know what you want and aim for it every day.

Through my job working at one of the major supermarkets, I have learned all kinds of tips and tricks to save money! Next time you visit a supermarket, bear the following in mind:

• You can save up to 50% on Sara Lee products by buying our house brand bakery items instead - they are made by exactly the same company.

• The meat is no longer as good quality and has gone up slightly in price. I would suggest going to a butcher instead and paying less for better quality.

• In-store baked items are marked down from 40-80% two days before their use-by date (this does not include bread or donuts)

• Buy bulk and buy less often. For example, if you drink coffee, wait until the BIG tins are on special and buy three or four. This will last you for ages and save you $40 and upwards on coffee alone in the long run!

• If an item seems a bit sparse towards the end of the week, chances are there is actually heaps out the back and it is going on special on the Monday, so wait to make your purchase then if possible.

• For those living alone, take another look at those frozen meals. They may look expensive at first glance at between $4 and $6 but then go and price the meat and all the vegetables. Remember also to take into account how much you have to throw out after a few days through not using them!

• If you want to see who makes what, look at the back of the pack to see which company owns it. Visit the Australian Stock Exchange (ASX) website and find out which other 'mini-companies' it has under its belt. They often compete with their own brands!

We are a family of only two adults who cook often with a large crock pot. However we do find ourselves with a heap of left overs after cooking a pot full of food. So, instead of filling the crock pot with enough food for one meal several times over, we now take two oven bags and divide our meat/chicken/fish between both bags. We add different flavourings to each bag then arrange both bags in the slow cooker and cook on low for eight hours. I have just made Chicken Korma in one bag, using drumsticks that were on special with an extra pinch of cinnamon and some chilli, and Mediterranean Chicken with olives in the other bag. The conflicting smells are surprisingly delightful and the final result is two delicious meals both cooked with the same amount of power I would have used for one. Any extras we don't consume straight away I simply freeze and save for a later date.

I am saving around $100 a month on my grocery bills, thanks to a few simple changes to our family meals. I wanted to reduce our food bill and after some thought came up with the idea of making two nights per week a '$2 Dinner Night'. For example, one night we will have something like toasted baked bean sandwiches or stuffed baked potatoes; the other I use up all the leftover vegetables in the fridge to make a self-crusting quiche. This reduces the amount of food we waste and the kids love it. Even the simplest meals can be delicious and filling and the savings we are making from our twice-weekly $2 dinners are well worth it!

While searching through the craft section in the Vault, I came across a contribution titled 'Loving keepsakes from recycled clothing'. This inspired me to write in and tell you what I did with my late husband's shirts.
 
He had a lot of flannelette check shirts, which he loved to wear in winter. I cut up the shirts into even squares, leaving the pockets on some squares - I replaced the pocket buttons with gold ones from my button tin. I then sewed the squares together and detailed them by sewing some bright blue ribbon down and across each section. After that, I backed the lot with a flannelette sheet – the end result was a lovely shirt rug!
 
I gave this rug as a keepsake to my seriously disabled grandson, who just loved his Grandpa to bits. My grandson could keep his treasures in the pockets I had left on the squares, as they had a flap that could be buttoned up.
 
Even though Grandpa's Shirt Rug is nearly worn out, my family will always think of it as a special keepsake. I thought you might like to read about my efforts; I just love making something new and useful from something old.

Make your own ricotta cheese and save at least 50% on the inferior product you buy at the shops!
 
Whenever I buy ricotta cheese it usually goes off in the fridge while I figure out what to do with it! But recently, Better Homes and Gardens featured a very simple recipe for ricotta made from scratch.
 
Ingredients:
 
2L milk
4 tbsp white vinegar
 
Method:
 
Heat the milk until you see small bubbles at the side of the pan. Turn off the element and add the vinegar. Strain the curds off the top and then drain through a butter muslin cloth. Really easy!
 
Two litres of milk makes 500g of ricotta cheese. While in the deli the other day, I noticed they were charging $1.00 per 100g, or $10 a kilo! I shop at ALDI, which charges $2.20 for two litres of milk – that equates to $4.40 a kilo, less than half the price of store-bought ricotta. Plus, I no longer waste the product that I buy and never use. It also sounds super impressive when you tell people you make your own ricotta from scratch!

I add a supermarket gift card to my weekly grocery list and use them all up to shop for Christmas! After doing some calculations I realised that the ready-made Christmas hampers that you pay for weekly cost three times their actual value, not to mention the fact that they can include many products you won't ever use. My new system for buying Christmas groceries lets me buy my own hamper full of items at the current price or on special.

Keep glass showers sparkling clean for months at a time by using baby oil. First, clean the glass on the inside of the shower well, then dry off. Next, take a soft cloth and smear a small amount of baby oil. I stress a SMALL amount to ensure no oil runs down to the base of the shower, creating a potential hazard. Pay extra attention to wiping the edges and bottom of the glass. Once you have done this, the glass will look smeary and quite awful really - until you have the next shower! The hot water heats the oil and smooths it out on the glass. I have never had the problem of any oil running down onto the floor, even after heating it. You'll find a very small amount goes a very long way. Basically, the soap scum cannot attach itself to the glass, which stays clean and clear for at least three months at a time. By needing to re-apply the baby oil only every few months, this adds up to a huge saving in expensive bathroom cleaners!
