If, like me, you hate listing on Etsy, might I suggest downloading greasemonkey for Firefox, and then installing some etsyhacks. I had been frustrated by not being able to upload more than one picture at once, the horrendous tags system, and worst of all not being able to copy all the information except pictures.
With Etsyhacks YOU CAN DO ALL THOSE THINGS.

Have a look at my listings here, and tell me what you think. It's going to be invaluable for listing greeting cards - the only reason I hadn't been selling on Etsy is because the listing is a pain in the arse.
