Spiral Bound Zombies

I made this quilt for our son from the Zombie Apocalypse fabric. I used the Illusion block tutorial as a guide but changed block sizes. The back was pieced from assorted matching fabrics that I had on hand. Spiral quilting was done with the walking foot on my 30 year old Kenmore. It was my first quilt using a walking foot. The size is 58" x 68".
