I sell prints of my artwork, along with T-shirts and accessories with my artwork on them, at Zazzle. You should check it out!
I also sell T-shirts through TeePublic (and truth be told, they’re a little cheaper than Zazzle despite having a bit less variety — up to you where you want to buy them!), and my designs can be found on Feminist Apparel as well.
NEW! I’m selling digital downloads on Etsy, and will be adding physical prints to the store in the coming weeks.
