For those of you who have asked, my binding tool (which is white but I think must be the same, I got it from M*): the long side is 8 3/8, the short is 6 1/8. Remember you have the little squared off end on the long side which probably accounts for the quarter inch difference. I know that's a weird measurement but I checked it three times and that's what it is. Even put my glasses on!

I love this. I made several of Jenny's Scrappy Table Runner pattern before Christmas and it's the most fun thing. This is just 4X plus a little tweaking. Can't wait to try it. I have the Kona Sunset jelly roll (solids) but think I may really, really need that Jinny Beyer too. oh well.
