|(Maaaaybe this is backwards and I had to trim the OTHER end!!)|
I snipped a corner as instructed, stitched a few stitches with the fabric right-side-down, and then used the thread as a tail to pull the fabric through the loop-de-loop-thingy. Having the thread tail to pull the fabric was genius, kudos to whomever thought up that tip! It was especially helpful since I have pretty large stumpy fingers. I'm sure long and slender fingers can maneuver this task better. I've only sewn through my finger once and I'd rather NOT go through that again!
