The directions on the Wrights website looked simple enough. But when I tried it today, it wasn't like the pictures!
I think I did okay on the corners . . . but what do are you supposed to do when you get to the end?
And should you start at a corner, or somewhere in the middle?
When you are on the second side and get near the end stop. Fold the corner down and miter it. It's helpful if you have a bit of water soluble double sided tape to stick it all together. Pins get in the way.
