Recently, I read a blog that said to use rubber shelf liners to cut shoe soles to sew to the bottom of slippers to make them slip-proof. http://hakucho.blogspot.com/2007/03/...r-walking.html
Today, I was at the dollar store, and found some rubbery shelf liners. Yay!
I got 4 rolls in different colors: black, beige, blue, and white.
Now, I can make slippers for my Grandma, and she can wear them without worrying about slipping.
