Once upon a time I tried to keep a journal of my finished projects.. it just never worked out. I now have a binder of old project patterns however. I find that very useful. I always make notes on patterns as I’m doing them with my changes, so if I want to make it again, I can.

I don’t know much about crochet, but I know with knitting, gauge is often important – even just for the feel of the piece, if not for size – so I always keep notes about what needle size works best with what yarn, and what my gauge in stockinete is so I don’t have to do a swatch every time. Now that I’ve been knitting for awhile, I know my knitting will always come out the same. When I first started I had to swatch everytime because I was still learning what tension my hands liked the best. If I were to do a journal, I would definitely have a section for that.
