Right now I'm looking into craftmaking as a way for my partner and I to make some money. Soap is a very interesting one, since as far as I can tell, making it is as simple as:
-snip-
Now, I understand that it doesn't sound that lucrative. But consider the fact that you could potentially make it out of things that are normally unharvested (rainwater) or treated as waste (ashes), and your oil could be had for like $0.30 per ounce or less if you make it out of animal fats (super quality beef tallow is $0.23 per oz), or harvest your own flax and make linseed oil or whatever. If you can get access to these materials, soap is basically a license to print money!
Or, you could just take the shortcut of buying bulk potash instead of making your own lye. Not even the crunchiest of hippie dippie boutique soap makers that I've met over the years bother with making their own lye when they're making soap. Is it a potentially handy skill to know how to do? Sure! But so's learning how to extract essential oils from plant material or rendering animal fat... but if you're not proposing doing that as well, why would refining your own potash be so important?
To be honest, I'm more interested in minimizing my use of linear production chains and I kind of stumbled on the soap-making by looking at uses for wood ashes.
I've just been playing around with the idea of living a lifestyle based on a philosophy that there is no waste. The exercise isn't necessarily to optimize production by outsourcing your labour by buying products, the exercise is to see what doing away with externalities entails.
Rainwater is useful because it can be harvested and purified for drinking, used for showering or washing in some cases, or redirected and stored to produce food or wood. That wood then gets burned for fuel, but what happens to it after that? You've got heat which you use for cooking and living, and ash, which makes up .4-1.3% of the mass of the wood, if you can usefully harvest that (
I suppose that composting counts), then you're one step closer to a closed, sustainable system.
In keeping with the exercise, ideally I
would produce my own essential oils and seed oils using redirected rainwater and composted human manure and organic waste for fertilizer. Offhand I know that flaxseed oil and animal fats (chicken, duck, goat's milk) could be produced where I live, and essential oils can be made from all the temperate spices and are probably commercially appealing.
The only problem is that that stored solar energy and those nutrients then leave the system by being sold rather than being redirected back to the land through graywater recycling, but the money could arguably improve the system by bringing increases in labour or improved infrastructure.
Edit: Sorry OP, back on topic:I've tried the following ways to make more money, and they almost all depend on having a skill that you enjoy, a network that lets you find people who will pay for that skill, and the time and tools to do it.
1. Live modelling. I make about $60 a month doing this. It's not going to make you rich, but it does let you meet new people and broaden your comfort zone. All you need here is time and your body and an internet connection to respond to a craigslist (or kijiji) ad.
2. Car repair. I've done brake work and filter changes and other minor stuff for friends in exchange for small favors and pay. Depending on your network and tools, this could be really good.
3. Personal training. I love working out. I've spent thousands of hours reading about weightlifting, dieting, endurance sports, injury treatment and prevention and the like. I also really love teaching and I'm very good at it. I currently work for $20 an hour doing one-on-one training with people I meet through work and...
4. Tutoring. I volunteer as an adult literacy tutor, and I also do math and upgrading. This is awesome because it's introduced me to a lot of adults who are willing to work hard at something and improve themselves.
5. Online surveys. This is kind of silly, but I made like $50 last year doing online surveys for Angus Reid Forum. I don't think I'll continue.
