I use a 6 x 24, June Taylor Strip Cutter, I can cut strips/blocks up to 12 x 12. I have a 2-12 x 24 I seldom use. A 9 x 9 square and when I want to cut strips over 6" I use a 8-1/2 x 24, then I cut squares whatever size I need. I also have a triangle, a couple of small square rulers. When I need a certain size I want to have right there. Since 2002, I make one quilt after another.
