I just made a baby quilt using this method. However, I didn't use the gathering stitch. I made a plastic template (heat proof), 1/4 inch smaller than my circle, and placed it on my circle pieces and "painted" the edge with spray starch. I ironed down the edges over the template and then used Sharon Schambers method of glueing down the piece, heat setting and then sewing with a tiny zigzag stitch. Came out great and was fast to do. The pattern was called Rainbow Garden and right now I don't know the author since I'm not in my sewing room.
