What do you do with extra blocks? I'm also glad I checked the measurements for the border before cutting. I use the Robert Kaufman app for my Droid phone and cut one less strip. I was able to use the fabric for binding the mats and runner. I hope to get the quilt top pinned Monday and will work on quilting it this week. The mats and runner are listed in my Etsy store. I'll have to do something with some of the other little blocks I have. It was fun to make this!
