I recently bought a bunch of these cards from Porridge Papers. I may have to send one to myself...
Be sure to check out their Sold items too. That's what I did to find these awesome Fancy Pants cards. If you see something you want just email them via Etsy. I recommend harassing them to reprint I'll eat anything on a stick or When we have money let's get boob jobs.
I also bought this pretty card from Invita Paper Studio.
The picture doesn't do it justice as the paper is so thick and the colors really vibrant and vintage. There is also lust in my heart for these gorgeous recipe cards. And if I was moving I would be all over these.
Some other Etsy card shops I love;
Cracked Designs: As if they weren't cool enough they are also from my WI - Nuff said.
Pish Posh Paperworks: Clever with cool typography.
Apakshop: The mellow colors and random graphics are fantastic.
