Double knit makes wonderful rugs that never wear out.
I have a rug that has over ten yrs of hard use at my back door
just cut into squares fold twice and sew down the middle take a piece of denim the size you want your rug to be and mark lines 1 inch apart and sew the little squares on it real close. let your imagination go wild as to colors. I hunted thrift shops for old clothes because you can't seem to buy good double knit any more.If you have double knit to get rid of pm me and i will pay for shipping it to me
