Veevus Iris Thread
Veevus Iris Thread is a thin, twisted, and flashy mylar integrated together with a fine, strong thread to make a great fly tying material for a variety of uses. Use Veevus Iris Thread for bodies on midge pupa or small nymphs, as a ribbing, or as a tag on salmon/steelhead flies. Euro nymph tiers, you're going to love the look of this stuff under a clear UV adhesive.
Use Iris Thread by cutting material and applying it to the fly by hand, or use a standard bobbin like any thread.
