What do you want to learn how to make?

I thought I might do a sort of how-to of the week (ish. Because I'm not good at doing something every week if I'm super busy), but I was wondering what people might want to learn how to do. I've got a few ideas that I just have to get some pictures for and do it to show you guys step by step how to make something. Or do something in general. Like sew a hem. Or put in a zipper. Or make a pattern. So if anyone has any ideas, tell me. Otherwise I'll just go with it and figure it out as I go along.
