I've never used one before. Clearly, as they've been around for
hundreds of tees, I'm late drinking the koolaid, but OMG they're
amazing!!! I have tried them before on my thumb or index finger, but
it turns out they go on your middle finger. I was able to FINISH 2.5
sides of my quilt binding soooo easily tonight, all due to my new
discovery. I'm in luuuuuurve. Seriously. If you've never used one,
it's worth trying.
