Sweet little postcard, Judith. I wore my 6.5 ruler out, and now have the 8.5 one, but is not so handy when trimming the smaller blocks. I have found the small Creative Grids rulers to be very helpful when cutting HST's as well...the diagonal line runs from one corner to the other. Smaller size is easier to manipulate when I cut tiny HST's. These two have 1/2" finished HST's. The first was made with waste triangles. [ATTACH=CONFIG]599031[/ATTACH][ATTACH=CONFIG]599032[/ATTACH]
