I agree. I think most people use a 24" x 6" ruler for cutting widths of fabric. But I still have trouble making multiple cuts. I tend to put a weight (litterally a Ziploc bag full of rocks) to keep the fabric from moving. I don't have a very long reach and this keeps it from moving around too much. I bought a ruler from Off the Wall that I like for strip cutting. It has two pieces so you can set the edge underneath and abut that to the edge of the fabric for cutting. So far I like it very much. I may still be off, but at least I am off the same amount for each strip.
Keep practicing. You'll find something that works for you.
