MFC Wing Material from Montana Fly Company is similar to MFC Flex Wing but is less ridged because it doesn't have the vinyl backing. MFC Wing Material is also a bit more cloth-like and folds better if you're tying caddis dries, for example, and want the material to tent over the body on each side. It would be great used for stonefly, hopper, caddis, or mayfly wings of all sizes.
To use MFC Wing Material, simply cut it to shape with scissors or use a wing cutter tool. Does not fray and is very durable.
Each package of MFC Wing Material contains 4 sheets which are each 2.75 x 2.75 inches in size.
