Congrats on becoming a gramma, Nannie Sue!
One of my friends has a toddler boy who is obsessive about playing with her hair. I forget what you call it, but it's become his version of a safety blanket, basically, so he's always touching it. It's really cute! At least she doesn't have to worry about misplacing a blanket!
Nannie Sue, just a tip on making the blanket. Be sure not to do it in stockinette stitch, because that will curl. ...happy knitting!
