I learned to do a twister with pencil and scissors. My granddaughter and I made one for her brother.
Then I made another and used my rotary cutter. That worked fine, too. I was really careful and didn't cut too far. I made a series of cuts on the row, then picked it up like a clothes line and did the little snipping carefully to cut the pieces apart. They need to be cut straight with the rest of the cut.
