Herter's Belgium Brand Imperial Tying Silk 46 Meters World's Finest Quality Madex Twist Tightens in WATER.
I bought at least four spools before finding a supply in the bargain buckets. Probably ordered half a dozen, and used up almost all the black.
There remains a few yards of black, a spool of white which has been re-wound (presumably after shrinking) and partly used, and an untouched spool of royal blue.
(I also bought some cotton turtlenecks from Herter's, and was outraged to discover that the upper parts of the sleeves cut off my circulation -- this "sporting goods" store sold shirts made for soft-handed women too weak to open a door!)
I found a tackle shop soon after moving to Lake City, but none of the fly-tying silks were marked "genuine silk", so I was afraid to buy them. Didn't see any hackle pliers, either -- might have been some if I'd asked, but I didn't really want hackle pliers.
Ooo, another place to hang out!
