Sock it to draughts with cheap 'door snakes'

With every winter, it's important to make our heating systems as efficient as possible. Draughts under doors (both to outside and to rooms not currently being used) let heat escape, driving heating costs up. Door snakes are often advertised at around $10 each. This means for a whole house you may be looking close to $100. Instead, you can use a pair of men's long, knee-high socks! These can be filled with rice (or sand if you have easy access to it). Either tie a knot or see the top to seal. You can purchase ind the socks at cheap shops or ok shops, use the cheapest rice you can buy and you can make a house-full for less than the price of one commercially produced door snake.

Put your nail biting habit to sleep for good

For most unconscious habits such as nail biting, hypnosis is often the best, cheapest and environmentally friendly cure for nail biting. No drugs, no chemicals and usable by any member of the family providing they are receptive to hypnosis. Some people cannot be hypnotised but they are very few and far between. A single personal session might be all that is needed, but there are some very good programs available in various formats for home use. Worth a go!

Student secrets to eating for $15 a week

During my uni student years I developed a menu-planning and grocery shopping system that allowed me the freedom to eat well, generously fuel my bicycle-based lifestyle, entertain guests regularly and experiment with new recipes, all within my strict food budget of just $15 a week!

It works like this.

1. Decide how much you will spend on your weekly groceries. In recent years I have had to increase my spending to about $21 a week due to rising food costs and CPI, but the system still works really well when I use it and is a great way to separate needs from wants.

2. Choose the staples and basics that are to be made every week as needed. These could include soy milk, tofu, sourdough bread, yoghurt, sprouts, hummus, fresh lemon cordial, Anzac bickies, gomasio or whatever else you require.

3. Give the ingredients needed to make these staples first priority when making the weekly shopping list. If you have a local food co-op you can buy mostly organic ingredients with minimal packaging in exactly the amounts you need.

4. Check what else is in the fridge, cupboard, garden or neighbours' garden and pore over your large collection of second-hand recipe books to see what can be created with these other ingredients. Recipes which require two or less extra (and inexpensive) ingredients are preferred and a list of these and their corresponding cookbooks/page numbers is made and stuck on the fridge. There will usually be a selection of mains, side dishes, desserts, treats and beverages on the list.

5. Give the extra ingredients needed for the chosen recipes next priority on the shopping list. Over time you will intuitively know when your shopping list is 'full'.

6. Once out shopping, specials of the day such as a big bag of discounted apples or cheap cooking tomatoes take third priority. If not consumed within the week, these can form the basis of recipes chosen for the following week.

7. Last priority (and usually only considered after the register shows you are still under budget) are those inevitable temptations that one wants rather than needs. It often helps me to take my recipe list with me and remind myself that I can make a delicious self-saucing carob pudding at home for a fraction of the cost of the tiny chocolate bar I am now contemplating. All of a sudden the money seems much better spent on a kilo of brown rice!

8. Back at home, simply cross the recipes off the list as they are made. There will always be plenty of food for dinner parties or last-minute guests, and the sometimes tiresome decision of 'what to cook?' becomes easy.

Using this system I have never run out of food or felt like there was 'nothing to eat'. In contrast, I have stayed at many houses where, despite having pantries and fridges which are bursting with food, the occupants have driven to the supermarket and easily spent $30 or $40 just to cook up dinner for the night.

Seems unbelievable? Try scratching every processed food item off your own shopping list and see how many more kilos of real food you can come home with for the same amount of money. Don't forget too, to keep an eye out for trees in public areas which are loaded with fruit or nuts. I have used the $15 a week food budget for stretches of up to a year at a time, which means I certainly wasn't relying on stockpiles of food from more extravagant days tiding me over. Necessity breeds creativity, and I am so happy to have been forced early on to examine and separate my wants from my needs in this regard. Even when times are tough, I know I can eat well!

Freeze your own grated cheese

To enjoy the convenience of pre-grated cheese, buy a block and grate your own - much cheaper than spending money on those costly supermarket bags!

Buy a block of cheese, grate it into a large ziplock bag and add a rounded tablespoon of cornstarch to the bag. Shake well.

This keeps the cheese from sticking together in a lump and you can store it in the freezer for as long as you want. It thaws almost instantly!
