Another shop?

Lately, i've been toying with the idea of setting up a shop on E-Crater or Big Cartel just for my deadstock jewelry finds. I have tons of earrings, brooches, and other stuff that's straight from the 80's (and some from the 70's) and i sell them at flea markets, but other than that, they just sit patiently in my storage closet waiting to see the light of day. I used to list some deadstock on Etsy, but i'm thinking i should keep the two separate.

E-Crater is free, but it's plain and ugly. Big Cartel costs $9.99 a month, but i can "decorate" the shop however i want. Really, though...do i want to add another thing to my huge to do list???
