I love this thing! Once I figured out how to use it, I fell in love. I didn’t really get the hang of it right away, but after watching some videos I figured it out. It is easiest to use when the item you’re unstitching is still tightly hooped. I buzz through the stitches on the back of the item, and then turn it over and rub my fingers over the stitches and they just come right up! It has saved my life many, many times!
