Re: First time using a furled leader and have a question
Axle's suggestion is a great, standard method and will work for your furled leader.
You can also make a loop in your fly line by simply folding in back and then whipping the overlap (about 3/16 - 1/4") with tying thread and hitting it with some flex cement or zap-a-gap. If you are fly tyer you already have everything you need and won't have to buy 20 yds. of mono that you'll only use 4" of. There are tutorials on youtube with tips on how to keep the overlap slim.
