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 several 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.
