And you might not know what a rotary cutter is. I didn't a year ago. Now I is a whiz at it.
Rotary cutters take the place of your large fabric sheers. You lay out your fabric on a special cutting mat (self healing) and using acrylic rulers, accurately measured, you cut your strips of fabric, extremely precise.
Here's my little secret, don't tell any of the women around here, but... I don't own a pair of sheers. I have a small pair of scissors I bought in a $1 store (for $3.00 !!!) for snipping threads at my machine. That's it.
Hope this helps.
