Here's a couple more postcard quilts to show off, plus a really clever adaptation of the pattern!
First up is this sweet thing by Tiffany/t.anne. I love the 'postmark' quilted up in the corner, as well as those wavy lines between the blocks that are reminiscent of curvy postcard edges.
Lynne/pieceful1 made this one, and I really like her simple palette. Read more about her quilt on her blog, pieceful.
