A good thing about acquired wisdom is that I knew to expect a bit of struggle while I worked out how to do things for the first time and couldn't find the switches etc, so I was patient while persevering. Class is good for quick answers to get you started and get the trouble shot.

Accidentally put two blades (stuck together) in the rotary cutter, and all my cuts were thready with cotton dandruff. Took a while to figure that one out. Is it normal? Is it my technique? Is it my cutter? What's supposed to happen? Doesn't happen with tutor's cutter, same brand.
