Here is a seller I discovered on http://www.etsy.com/
Helen is the creator behind hmsdesigns http://www.etsy.com/shop.php?user_id=5256671 is from the U.K. and is a textile designer that dabbles in mixed media as well.
She creates greeting cards, aceos and wall art combining elements from the beach and sea, together with lovely hues and textures. I already purchased 3 cards from here today and plan to place them in a frame as a trio for my seaside place...
p.s. She also has some romantic silk heart hangings... :)
