Two items:
Wonder Clips.... When I started to sew binding by machine, these were a time saver and kept everything precise. Had them for a year before a I opened the bag.
Staletto.... I bought one when I first started quilting because Ms. Burns recommended it (lol) over 2 years ago. It sat next to my machine until about 4 mos ago and i decided to try it when sewing Mini's or tiny piecing. Good grief....works awesome and I can get my big fat fingers out of the way. Realized that, without it, I was guiding my fabric wonky under the needle because I was trying to control it and not let the feed dogs guide it. I use it to sew binding on too. Love it!
BTW...been using Roxanne glue baste when appliquing since the beginning and would not attempt any other stuff. Love it...
