I'm just in love with printables and have scouted out another free one for you today!
This is such a cool wall art idea and easily customizable with what you have on hand! No postcards? Try using greeting cards (there are SO many amazing handmade/letter pressed/screen printed cards these days), gift wrap, patterned scrapbook paper, etc. -- the sky's the limit!
Sending this postcard pillow to someone special would sort of be like sending a big hug. Avaliable at Olive's shop on Etsy, each 14" x 11" pillow is customized to your specifications, including message address and post office cancel. For more information about the pillow and to order one, follow this link. ($32)
