To use Swiss Straw Synthetic Raffia tie in over the body of your nymph then use Semperfli 0.2mm Fly Tying Wires or monofilament to form ribbing for your fly. Swiss Straw Synthetic Raffia makes great wing cases and can be wrapped around the hook to create bodies without adding any weight to the pattern. Another alternative use is for very realistic looking wing buds on buzzer patterns, you can color it with a permanent marker then coat with No Tack UV or varnish for a stunning effect
