70s polyester knit fabric remnant, yellow, double knit

Vintage 1970s yellow double knit polyester fabric that has been cut. The part that’s uncut is 35” long and 65” wide. The part that’s cut is 30 1/2” long and 201/2” wide. The grayish specks are part of the fabric. They can be seen on the front and the back. It’s not dirt. From a smoke free and pet free home. There are other 70s fabrics in my closet.
