I bought the GripStrips to put on my June Tailor Shape Cut, which I cannot do without. I put one at 2-1/2", 5", 7-1/2" and 10", plus at the 1/2" and after the 11-1/2", because it was shifting on the fabric. Spacing them like that, it helps when I'm squaring up the fabric at "0", then when I'm cutting 2, 2-1/2 and 3", then 4-1/2, 5, 5-1/2 and 6; then 7, 7-1/2, and 8, then 11, 11-1/2 and 12. My strips are much straighter now.
