So, it's no surprise that there are a lot of different versions of this pattern out there. If you've recently began the journey (re: madness) into tying your own flies, then this nymph is one you want to know how to tie.
Here is a really well made video showing a very nice way of tying up this pattern. You can't go wrong by following the directions here & this version of the nymph is a great one to carry in your fly wallet.
So sit back & enjoy. I seriously wouldn't want to spend a minute on the stream without having one of these nymphs with me, because it's just one of those patterns that will work on days when nothing else will.
