American Thread Co., introduced their Star Blend Yarn in 1948.
"For knitting, crocheting, tufting, weaving, braiding. 75% rayon; 25% cotton in a range of fast colors, advises this 1951 newspaper advertisement.
The yarn never gained great popularity and fizzled out well before 1961 ... according to this salvage sale notice.
There are a couple patterns in the shop that call for the Star Blend yarn. I would recommend you substitute a heavy rug yarn, in brand of your choice.
Thanks for dropping by.
