I may be completely crazy but I just opened another store on Etsy - Feeling Artsy Studio - where I'm planning on selling my original artwork, prints and also custom artwork like portraits and such. It'll take a while to get it filled up and I'm not sure when I'm going to work on it, but I'm not worried about it. I'll have lots of time to sleep when I'm dead.
My other store is not really full with lots and lots of items but I wanted a separate one for artwork, sort of like a niche. I'm not sure whether I needed one or not. We'll see how it does.
