I recently purchased a large lot of vintage fabric from a local estate. Most of the fabric was purchased in the late 80s or early 90s. This listing includes three pieces of double knit t-shirt fabric. It is fairly thick and soft and most likely mostly cotton.
Two of the pieces are 32 inches long and 68 inches wide. The third piece is about 40 inches long and 66 inches wide. The fabric is in good vintage condition.
