I used every last bit of that JR, I literally only have slivers left. The pillow is the last pieces I was able to get out of them. I am going to use the green and blue stripes in a 4-patch for the back of the pillow in the same way that the quilt blocks are set. It's just pinned onto another pillow in the pic until I can get a form for it.
This is on a full sized (double) bed.
