I'm not talking about coming up with something and dismissing it as stupid, but a complete void. I've got writing ideas, just don't feel like messing with them right now. I've also got sewing ideas, and I do need to get on those before I'm stuck with wearing something ugly for the sake of modesty. What I don't have is drawing ideas. I can write about something and describe it as much as I like, but it engages a different understanding than the type needed to draw it.
