Thanks to Judy, Judy, and Jane for your advice (Jane - yours was the most tempting!). I ended up removing all the setting triangles and starting over with a different fabric, cutting the triangles just a little larger. Everything fits perfectly now. As I was ripping out the old fabric, I got to thinking that there might have been a little polyester in it - it just didn't have the same feel as the cotton, but the color was perfect so I went ahead and used it. It is now in my trash can. I had to switch machines mid-quilt also, because my trusty Janome (which I just bragged about to someone here on the board) decided to start breaking the thread after sewing for about 3". My seam allowances looked to be the same though, thanks to my cute little Featherweight standby. This board has always been my backup when I run into trouble and I've learned so much over the years. Thanks again! NancyH
