For the price of all those different ones you 'may have to' purchase, consider both the Shape Cut Plus and/or the Shape Cut Pro (slots are 2 1/2" apart, but the ruler is 20"x23"). I have both and use them more than my Altos Quick Cut 2. Fabric can be layered to your preference. Cut binding strips, charms, layer cakes, jelly rolls, hex's, triangles, etc. etc. I also use them to cut fringes on fleece blankets. If I had purchased these Shape Cut slotted rulers when I was first starting out, I would have no Altos Quick Cut 2 and only a few other rulers hanging on my peg board. We learn as we go.
