A friend and I ended up starting a knitting club where we used to work, and I taught a few people to knit. We weren't very well prepared. I've taught more people to knit since.

The one thing I definitely do differently now is teach people to knit with cotton yarn not wool. You can see what you're doing better and unpick easier. Also, if you knit smallish squares, they're finishable quickly and are either facecloths or dishcloths depending on whether you use nicer knitting cotton or cheap craft cotton.

They're actually pretty good facecloths to use with face/body scrubs as the loose knit means the pumice/ground nutshell/sea salt or whatever particles will rinse straight out. I now knit them specifically for myself.
