Last winter while wintering in Az. was the first time I saw a qillow and made 3 of them for 3 of my grandchildren. I adjusted the size according to the size of child. I added an 2 inch onto the pillow to give more folding room on the bigger ones. Also add enough batting for warmth, for those who want to use pillow as a foot warmer. My grandchildren use theirs all the time from watching tv, in bed and even take on the airplane as they fly to Texas regularly.
