I love gadgets, especially quilting gadgets.
My favorite so far is the Bendable Bright light.
It is a small LED light with a flexable arm that sticks to your machine. It really adds so much light. It is great for working on darker fabrics and helps you to see your marking or hera lines.
I have also been using the finger tips from Playtex Living gloves to machine quilt, just cut to the size of your fingers. They work as well as quilting gloves and they don't make your hands as hot.
