One of my "jobs" is to design the Block of the Month blocks for my guild, Empire Quilters in NYC. This raw-edge machine applique block is our block for October. I made this tile quilt as an experiment to see what would happen when it was machine washed and dryed. I know it's pretty big for an experiment, but I was having so much fun.
I should have used a zigzag stitch to applique the patches, or sewed a little further away from the edge (more than 1/8"). A few of the "tile" edges came loose in the wash and needed repair. The quilt also needed a trim to remove lots of frayed edge threads. But that's okay. It has a soft, shabby chic look now, and I like it. I think it looks fabulous from a distance! Haha.
If you like the look of tile quilts, you might be interested in a book called: Tile Quilt Revival: Reinventing a Forgotten Form by Carol Gilham Jones and Bobbi Finley, published by C&T. The quilts in this book use the needleturn applique technique rather than raw-edge.
