h/t to John Newbury from FB re this knot tying technique: The Hemostat Knot. This might be particularly helpful when the finger tips are frozen, or for general use.
For the beginning fly tier, you would be well served to practice your tying techniques while tying a limited scope of patterns. The temptation is to tie every pattern in that book and more that come to mind. Tie this and tie that. If you were limited to just tying as a past time with no opportunity to fish your creations, then tie hither and yon, but otherwise I would stay toward basic nymphs, dries, emergers, streamers and flymphs/wets (or, the basic patterns for the species you chase….it could be a variety of streamers only for a predatory species). This way there is a practical benefit to your targeted tying.
Flymphs: this style of ‘wet’ fly is worth a study on your part and worth a lot of tying. Selection of hackle and style of body are the two key considerations. Sparse patterns for almost dry fly presentations have/had their place. But, buggier dubbing and softer hackling offer a great deal of animation and life. A flymph can fish from the bottom up to the top with the correct presentations: Leisenring Lift.
A couple presentation considerations: study spey (two hander) casts and research their applicability to a single hander. Jean Paul from Roughfisher mentioned this the other day and it true. Line handling with bigger flies or more staged presentations can be easier by moving line, dumping it and then rolling it out into a zone. Research this. Also, for the stream fishing angler chasing primarily trout there is a tendency toward only using a floating line and rarely a sink tip. I use five lines for stillwater but severely limit myself on rivers when chasing trout. (I carry multiple spey line heads). But, a readers comment about using sinking lines and manipulating the fly up through pools and rapids reminded me of watching an old timer fish streamers with a clear, intermediate line to fish streamers on a river (something I would normally only use on a lake).
