When we had to place my MIL in a nursing home due to dementia, the director of the home saw the nice, quilted lap quilt that I had made her and strongly suggested that it not be left in the nursing home, as it would likely disappear. I would make Grandma a simple bright lap quilt out of scrap squares and flannel back and would tie it (no elaborate quilting). One of the local churches donated some of those to the home and the one given to my MIL stayed around for a few weeks then just wasn't there one day. But while it was there, my MIL loved the bright colors made of scraps of polyester. Maybe a more appreciated and comforting gift would be a memory quilt for you MIL out of fabrics from Grandma's clothes. It is really hard to see your parent go into a nursing home.
