Spent 4 hours chasing a crooked pin pattern that came down to my cutter being 1/16 off
I kept re-centering my 2.25 inch circle designs and the pins still looked tilted on the card, and it turned out my cheap circle punch was cutting slightly oval the whole time. A guy at the craft fair in Tucson told me to check it against a quarter, and sure enough the gap was bigger on one side. What do you all use to check your punches before you ruin a whole batch?
