How to Use Poly Yarn for Fly Tying

Poly yarn has long been used in fly tying. A common misconception is that "poly" refers to polyester, but it in fact refers to polypropylene. This material stays buoyant when wet (unlike our wool yarns), which is why it is sometimes referred to as floating yarn. It's great for use on dry flies, but it's not so buoyant by itself that it can't be used on wet flies or streamers.

Here at FlyTyingYarn.com, we sell several different colors of poly yarn, which you can find here.

We plan to make and share our own examples of flies you can tie with poly yarn. Until then, here are some fly tying recipes and videos showing different uses for poly yarn. Each link will open in a new tab/window.
