I found this at a thrift store. It was the wooden part of one of those lap desks where a pillow is supposed to be attached on the other side. There were 6 large rough Velcro pieces on the other side of this wooden lap desk and the Velcro was stapled in place with a heavy duty staple.
I used the shape of the wooden lap desk to create this pillow and sewed the soft Velcro pieces to the fabric in order to attach the pillow to the Velcro that was on the desk. I stuffed this pillow with fabric scraps. It works great!
