After I have selected the flies I want to tie from the catalog or online viewing, I will search for a tying video for each fly on Google, You Tube, or Vimeo, just to name a few. I will watch the video through the apps on my big screen tv and tie along.
If I am traveling outside of Illinois on a fly fishing trip and want to know the flies used on a certain river or stream, I will Google search for a fly shop in that area. Example, Au Sable River Grayling Michigan Fly Shops brought up Bob Linsenman's Au Sable Angler, Streamside, etc. You can visit their fishing reports too.
I don't know about you, but I cannot stand cabin fever. I hope this information helps you get through the winter and improve your fishing adventures.
