Congratulations ! I find fly tying is a really relaxing pastime. Sometimes it is nice to tie flies just to tie flies, or as a creative outlet.
For me it started while trying to "repair" some jig buggers I had bought where the hackle was starting to unwind. Next thing you know I was reading a Kindle book on tying various flies. I also wanted to tie my own tenkara kebari.
I think a lot of people probably start with woolly buggers of some sort. Fortunately, buggers don't need to be pretty to catch fish ! Some of the ugliest flies to human eyes can still catch fish. And the fish can still turn up their noses at pretty flies, too
I learned a lot of basic things from youtube channels like tightlinevideo. There are lots and lots of fly-tying videos/tutorials/step-by-steps/recipes online, and I have a huge stash of bookmarks.
