I used 20 neutrals, and did an estimated guess on what I'd need cutting strips, ended up with 303 squares.
I cut the strips, then paired them up and stacked them, then lined up three "rows" and used my JT shape cutter to get the diagonals - then I used the EZ triangle to cut the straights on each row separately. I was getting tired of picking it up and moving it, then remembered the little handles I had tucked in with my rotory cutter stuff.
I'll trim them after supper. I have a tendency to go a bit too scanty on my seams, so some are right on 2", and some a hair larger. At least that's an easy thing to deal with.
I've never used the JT Shape Cutter before, but I recently read about what others do with theirs and figured it was time to give it a try.
