I make rugs from 2 layers of denim--I call them my back door rugs as they work great in my farm mud room. Yes it's hard on the hands. Last time I was lazy and washed the rug--when I pulled it out of the washer I had an aha moment. Hair is weaker when wet--what about denim? Before putting it into the dryer I clipped the edges-yes yes yes alot easier on the hands. Give it a try next time.
OBTW--a nice way to remember a special person. Thanks for sharing.
