cafe press

Does anyone have an account there? I just opened my own 'store' yet ... am completely clueless as to how I 'make' stuff. I've uploaded some photos into my ... account file there, but when I go to 'customize' stuff, it just adds it to my cart (like I'm making a mug for myself, instead of to sell) and I've faffed around with it for over an hour and am still clueless.

grrrrr

Any advice is appreciated.

BTW: I know I can't do anything that's copyrighted, but I have enough stuff that's SORT OF HP or other fandoms, but is vague enough that it should be free use. And I opened a custom store, not just an account.

Thanks in advance!
