I just finished customizing my Big Cartel store. It was a lot simpler than I thought it would be. Since I am not HTML coding every single day, I sometimes need to give it a couple looks before I know exactly what to do. It went together in a snap. I think it integrated well with my site so you would never know you moved to another site unless you looked at the address bar. It looks much more professional than what I had before. It costs $9.99 a month which is a hit for someone just starting out, but I think it will workout in the end.
