If you watch The Midnight Quilt Show you know what these are. They are Angela Walter's quilting rulers. The little whatchamacallit in the center is a special quilting foot you have to use with these rulers.
I've been free motioning the heck out of Daddio's wedding ring quilt with mixed results. The rulers will give me some more options when it comes to borders and straight lines. There are just some places that wiggly squiggles don't work.
I also threw a new ironing board cover in that Amazon order. The hot pink one that came with the board was blinding me. I needed something neutral and soothing while I am wrangling those tiny Jane pieces. This one should do it.
