I have recently taken on a small ton of crafting projects. And by that I mean a large ton. I had to grab a composition book and a pen to write them all down. I do not want to forget anything. So now, when I have an idea, I just write it into the appropriate section of the book. I have sections for little dolls, for paintings, for clothing, and woodwork. It's getting interesting, but I like having all sorts of different things going on, it keeps my mind active.
