The only shop layouts I can find are on Subetalodge, and you're not allowed to edit them. Is there any free CSS I can use for my gallery. I really hate the default look.

You can't theme shops/galleries anymore.

I've been able to? Under "Edit Shop" You just slap the code into the Text/Description box provided.

I just don't like any of the pre-made stuff I've come across.

Can you link me to the shop?
