I used 2 1/2" strips that I cut from 5 different yardages, but could have used a Jelly Roll. I added 1 1/4" sashing, just to give it some punch. I used a hand towel backing for the first one, but settled on a remnant of terry toweling for this one. I added 2 1/4" binding. Overall, it measures 17" x 27". Seriously - when you have something this pretty to look at while you're washing dishes, the task doesn't seem so bad :-)
Next on the list: kitchen floor mats, and then bath mats!
