It started when I found this fabric at Hancock's of Paducah, Windham New Town Farm Crazy Quilt Panel. I love it, so folky and wacky. The border around all the shapes is what really caught my attention.
Then I checked out Crazy Quilts by Cindy Brick from the library and found a pic of this quilt, the Hattie Burdick quilt. Just amazing. The book calls these type of quilts tile, or stonewall quilts, and explains the that they're appliqued shapes with white space left as the "grout" between.
And look what I found when I googled tile quilt, a new book out this year from C&T Publishing, Tile Quilt Revival by Bobbi Finley and Carol Gilham Jones.
There's more to read about tile quilts here. I'm very intrigued. I want to try this.
