Originally used to create wings for spinner patterns, wing film is ideal for flash back nymphs and scuds and the best material we've used for poxyback nymphs. It's also awesome as a wing/overwing on terrestrial and stonefly dries and as a wing material for drowned spinner patterns. Color the bottom side with a Sharpie marker for exciting color effects!. Each pack contains 2 sheets, approximately 4" x 5" per sheet. View tying instructions for the Lehigh Poxystone above here.
