This bouclé yarn is from Charles Y. Butterworth, a New England-based supplier who specialized in novelty yarns. They were active in the mid-20th century. This is labeled as product #7220, but otherwise has no other identification. It is rayon or possibly rayon/cotton blend, in a medium blue. It probably dates from the 1970s. This should work especially well as a weft thread. 

The tube weighs 6 ounces. It was probably 8 ounces originally, so it has been partly used. The estimated yardage remaining is 525 yards.
