I found this craft yard package at work while cleaning out an old locker from a craft class called "Fun with Fibers." The package contains 10 skeins of natural colored yards (2 of each).
It seems to be a wool polyester/nylon blend, it's soft and has the sparkle of Antron yarn. There is no way of knowing since the packaging gives no clue of the blend, not could I find the product online.
I compared it to Veniard's No. 477 and it looks close. I have to tie a few Sawyer's Killer Bugs with the 3 closes matches and see which produces. Needless the yarn looks very buggy and should work for several nymph patterns.
