When I make them, I make them the WIF and then long enough to fit over toes, usually 50 or 55." I like to see them able to tuck into the sides of the chairs and or to use to cover legs and arms if lying in bed.
I'm going to share y'all's suggestion of the ties with the nursing home here close to me that I make them for, that's a great idea. Never thought of it nor have I seen them, bet the VA Hospitals would like that, too.
