According to the label, Star Spun is a blended yarn, 69% Rayon, 23% cotton and 8% Metallic Thread. There were 60 yards per skein.
From appearance, I'm going to suggest that this is a variation of Aunt Lydia's Heavy Rug Yarn. In 1955, when Star Rug Book No 134 was issued, the blend on Aunt Lydia's Heavy Rug Yarn was 75% Nylon and 25% Cotton, a 4-ply yarn. The design variations where I've seen this yarn used in patterns is the contrast color and the bit of sparkle added by the metallic thread.
So, I would say that should you wish to make a design (probably rug) that calls for this product, that any heavy rug yarn that meets the gauge will work. You might even be able to find one with the sparkle.
