A recommendation seen on most forums is to pick out 5-10 that you want to learn how to tie.
Buy the materials provided in the recipes of those flies.
These materials are now the building blocks for tying different fly patterns in the future.
This list of beginner tying materials is simply a list based on my 30+ years experience in fly tying. The list provided below is for a new tyer who wants to tie trout flies but can spill over to different genres of fly tying. It is a BASIC list. Could other items have appeared on the list? Of course they could but that's somebody elses list. Other tyers will add or subtract materials to their liking. So be it. Remember its a BASIC list of materials. It contains materials the can tie hundreds or even thousands of fly patterns.
This list is in no order of preference. This list is provided for your convenience and in no way requires you to buy all tying materials all at once or any materials for that matter. It is also a generic list of materials as I really don't have any preferences as to what brand of materials you buy.
Eventually you will need materials if you want to continue tying flies. The list may give you a head start as to what you might want to buy
Again, you do not have to buy the entire list all at once!
Buy what you want when you need it!
1. Hooks (in different styles and sizes)
2. Thread (6/0 to start in black & white)
3. Pheasant Tail (center feathers when possible for the longest fibers)
4. Peacock Herl (eye feathers and strung herl)
5. Marabou (blood quills are better)
6. Deer hair
7. Elk hair
8. Buck tail (in different colors like red, yellow, or white)
9. Lead or non-lead wire (in different sizes)
10. Ribbing wire (silver, copper & gold)
11. Rooster Hackle (grizzly, brown, white & dun) A good option is an introduction pack
12. Hen neck or saddle (grizzly, brown, dun etc) (great for soft hackle & wings)
13. Hungarian Partridge Skin (great for soft hackles)
14. Dubbing dispenser of hares ear (various colors) & superfine dubbing for dry flies
15. Gray duck or goose wing feathers (used for wing cases)

20. Floss (1 strand or 4 strand in assorted colors)
21. Strung hackle (practice wrapping hackle with this. cheap alternative to the pricey hackles)
Poor quality materials are destined to discourage beginner tiers and cause greater expense when the time comes to replace them. Buy the best you can.
