You can find anything from clothing, vintage pieces, jewellery, photography, art, furniture and even food!
Some of my favorites sellers are:
Blulima creates some great silkscreened and giclee prints.

And yes, I have the infamous Keep Calm Carry On. And I really like it. I had it in my living room but moved it to my kitchen and it seems to fit there the best. I also bought my sister one for Christmas. Hers is charcoal grey and she has it in her kitchen too!
I purchased both of them from sfgirlbybay.
Here it is in my kitchen! Sorry about the glare.. and the ugly pipes.. and the plug.. :)
Jen Ramos' etsy shop made by girl has some great prints too. I love the hello in different languages. My favorite though is the Alphabet print. I think it would be the perfect baby shower gift!
