Sticky notes are kind of fun. If you don't always feel like writing a lot, this can be a quick fix and get you where you need to go.
I think I have also used clustering for poetry.
I always love writing on a large size index card too. I was doing this a lot earlier in the year.
I need to do this later today. I may even get a chapter in! Or if I don't it's because I turned into Chicks With Sticks for today and am going to work on another shrug. Actually right now, I am working on a dress for an American Girl doll. I'm on the skirt part and I am very much questioning the size of the skirt. It seems way too large, yet I am working on the right size needles for the project.
