I recently came across this free Beginner’s Guide to Fly Tying in PDF form that is from the Southern Wisconsin Chapter of Trout Unlimited. Pretty basic and helpful little book for anyone just starting. It also includes a basic materials list as well as a hook conversion table. Oh, and for those of you in Wisconsin, there are stonefly, caddis and mayfly hatch charts. A lot of good info to get you Cheeseheads (and others) started in fly tying or fly fishing. Last but not least, to show your appreciation, please consider joining Trout Unlimited. You can learn more at https://www.tu.org/
