Yes, use the chart. Cut the pieces the size the chart says. Once you cut the pieces as far as you can on the 1st strata set, turn that same set around and cut some more. It is very helpful if you can walk around your cutting area. What I mean, is once you cut the 1st set, if you can walk around the table and cut from the other side, you won't have to move the set. Wish you were in the US, I would be able to explain it better ear to ear.
