Just for investing? Anyone know any good crafts?

Is this forum and everything involved just for investing? I'm wanting to get a little non-profit shop going where I live for those on social security and SSI making crafts that would be sold at craft shows. This would help them suppliment their income a little bit. I also have a sister that has downsyndrome. There's nothing for these ppl to do so if I came across some crafts for her to make, she'd be able to be around others like her (She loved school and her friends), it'd be really great! I'm mainly looking for some crafts that are fairly simple but would sell to break even to do something like this.

Any suggestions?

I come across a lot of ppl on SSI as I am a volunteer driver and drive medicare patients to the doctors on a daily basis. Lately it's been a lot of people that have cancer.
