Our church made post-mastectomy pillows and donated them to the surgeon of a woman at church. She loved her pillow but said it kept sliding around and she would loose it at night. I put straps on each top corner to tie on the shoulder. She loved it. We also put pockets on each side of the pillow to be used for ice or heat and the other side for book, chapstick, tissues, cell phone... Surgeon loved them and requested more.
