Great advice from the guys –
It sounds like you already have a lot of options with the materials you have.
What kind of fish are you chasing?
Other inexpensive materials for Saltwater:
bucktail about $5 for a tail (a zillion uses) a bit less expensive per fly than EP fibers and you don’t have to worry about snarls
strung saddle hackle,for tails on deceivers and other baitfish patterns and can be wound around the shank on flies like Seaducers. Aabout $4 for a 1/4 oz pack, look for "saltwater" length 6-7" inches long
dumbbell eyes, or a length of 1/8" beadchain from a hardware store, (cut the length of bead chain into pairs with the cutting edge of a pair of pliers). Use dumbbells or bead chain as the "eyes" on a clouser minnow (or other inverted flies for redfish, bonefish etc) and other patterns like Whistlers
Skein of acrylic Rug Yarn from a craft store (you can often find them for a $1) for tying crab flies like the Merkin (cream or light tan)
Card of flat Braided Mylar for bodies on flies—this is sold under a variety of names Diamond Braid, Boidy Braid, Sparkle Braid etc. It comes in a variety of metallic colors, (pearl and silver are very useful). This is easy to use, and pretty tough (stands up well to teeth) about $1.80 or so per card.
Here are some SW basics with tying instructions from our pattern library using inexpensive materials:
(great all around baitfish pattern) Can be tied with saddle hackle tail as here in the original or as a “bucktail” deceiver with a tail of bucktail.
to imitate small baitfish that big fish feed on like anchovies, pinfish glass minnows and the young of larger baitfish. It’s a very simple pattern consisting of a body and wing—note that using the same size hook, a size 2 for example you can imitate baitfish that are 5-6” long by using a tail on patterns like the Deceiver or Blonde as well as 2 ½-3” long baitfish in patterns like the Glass Minnow with just a wing and no tail. This allows you to use a good-sized standard shank hook on small baitfish patterns for big fish. Although the original used bucktail, the “style” of tying can be used with synthetics, marabou, craft fur, rabbit strips, arctic fox etc
another small baitfish imitation, a good choice for weeds and shallows.
(a fly that fishes well around mangroves and flats for redfish, snook etc over off -hore wrecks for cobia, and a decent “single use” shark fly)
