After you have the squares all sewn into the rows that you want, I cut only one row at a time, then sew those together before starting the next row. that way I don't make the mistake of sewing wrong pieces together. Also, it makes for a change of position for my tired back. Hope this helps? My little twister template was made by the quilt store out of thinner plexiglass than the real template. I put my own grips on the bottom. The larger twister does have thicker legs and does make it hard for cutting. I think I will take those legs off and just use some thin grips that I use on the backs of pictures.
