I have used it cut into 41/2 squares and piece randum colors, backing old jeans, no batting, tied with light weight yarn. have had them in trunk of cars, behind truck seats. used for picknick, change tires, laying on under truck for road side repairs, kids naped on them under pine trees, wraped sick pets in on trip to vet, dogs layed on them on the way home from a swim in the ocean, even used one night when a cow gave birth and died shortly after, kept calf safe and dry on the trip to his foster mom. They are indistructable!! Had to retie one but fabric is still going strong!
