I normally make my bindings for a quilt double the width, and then the length plus some around it so I can miter the corners.
A while back I signed up for a class with Lauren Vicek to make a small wall hanging with lots of handwork with glittery sequins and beads on it. I was dazzled by the sparkly tiny flower sequins and the way everything looked on that small piece. When it came to the binding, I decided to use 4 strips of single fold binding so I could use one fabric for 2 sides and the other 2 sides of another fabric. Everything was going well until I had to put the project aside for several months.
When I picked up the project again to finish the 4th side of the binding, I was stumped. I couldn't remember how to do a single binding and finish off the corners. I had done it on the other sides without problems, but just could not remember. I tried folding the binding in half, but then it wouldn't reach over the edge around to the back. Not only that, but even looking at the other corners, I couldn't figure out how to finish the ends.
After fiddling with the binding, it finally dawned on me that I was trying to put a double binding on instead of a single layer binding on as I had with the other 3 sides. Duh! From there, it was easy to figure out how to finish off the ends. Whew!
