If you are talking about polyester double knit - then yes, you can use it - a plain block would be best - and yes, it wears like iron. A friend made my DH and I a double sided double knit quilt to put on wooden bleachers at our local dirt track (stock car race track) - she machine quilted it and put some sort of batting in it and we would sit on it and not get splinters, etc. Don't know what ever happened to it but my guess is that it is still around somewhere - maybe a dog bed. One of our kids probably has it.
