No, I haven't started yet. I just received my package from my first 1.5" swap, so it will be a looooong time before I have enough. Right now I'm in the middle of cutting for my current project (Buckeye Beauty). I really don't like having more than one project going at a time.
Go to the Picture section and enter Postage Stamp Quilts and you'll see quite a few options for making this quilt.
If you're interested in joining a swap, Missi has another one going right now. Pieces aren't due until March! Here's the link just in case you're interested.
