I'm also fairly new to fly fishing and was also wondering where to buy tying materials. I've tried several ones and they were all pretty good.
Couple weeks ago I bought this trout season 2018 kit from The Popper Company. It contained a lot of finished flies, tying kits , materials such as epoxy eyes, popper bodies, fluoro fibre, etc.... .
I think I will have close to 100 flies and I paid 120$ for it. That is a bargain, I think
Here is the link to that kit
