Crafting Ideas

Has anyone learned to crochet as an adult? My grandmother used to crochet such beautiful things, and it's something I've always wanted to learn to do. I've even taken a few classes (years ago), but I just never got the hang of it. I think I want to try again. My biggest issue is what to actually make. I'm pretty minimalist in my approach to stuff, which stops me from trying a lot of crafts that interest me. I just don't want the things I make hanging out in my house.

So, if you crochet, what do you make? And if you learned as an adult, how did you learn?
