handkerchief corners - first square

I finished the first square of my handkerchief corners quilt this afternoon...only 87 more to go. If all goes as planned, this quilt will measure 64" x 88", so it should be about twin-sized. Each square will measure 8" x 8" once they are completed and sewn into the quilt. I think I'm going to try using a higher loft batting on this quilt to make it puffier and warmer for the winter. I've only ever use the thin cotton batting, so we'll see how it goes.
