I also determine how many cuts I can get from each fabric for the pattern I'm working on. Then I cut the amount I think I'll need plus a couple inches more as I always starch and then press the fabrics so I know it will shrink a little plus it might not have been cut straight at the store. I'm OCD when working on a pattern. I write down how many strips from each fabric plus how many cuts from each strip on a piece of scratch paper. Every page that comes out of my printer if it has a blank side, it becomes scratch paper. I cut that into 4 pieces evenly. As I get all the cutting done, I check mark along side it. Borders, sashings, bindings, everything. I told you I'm OCD and this shows it.........lol.
