NO, I start by cutting the largest piece I can get first. say strips 10x10 inch, 5 inch, then 2.5 strips. I can cut the 5 in blocks when needed. The smallest I cut is 2 inch strips, No blocks. I will cut 2.5x 5 in bricks and squares out of the smaller pieces. I keep strips by color.
Trust me, if you haven't used it in 2 yrs, cut the darn thing. LOL. Make a Log Cabin or something.
