Art n fanwear

I started selling art on Redbubble because I wanted fanwear for the Attolia series by Megan Whalen Turner. I think I’ve expanded a bit since then:

It will be a year in November, and I have had a lot of fun with Redbubble. I plan to keep expanding and keep getting better at art.

I’m also thinking I need to tackle Attolia again and start working up some more fanwear designs.

Are there other books that are unrepresented in the fanwear realm that you think I should do?
