PDF worked for me. Thanks so much for the chart. Do you know if there is something out there for HST's that I already cut the halfs. I just can't seem to cut them to fit the quilt top they s/b 3 7/8 each square. Everything I see is how to sew them when they are a square. I know I've just gotten myself confused since I can't get rid of this stupid cold. I feel so stupid that I can't get it done right. Thanks for any help. Sue
