Here's another great Fly Tying Tip for your readers.
Thought I'd better send you this photo of the pens that I use to colour in certain fly patterns. Note: the Orange one in the photo is the one I use for the Alevin and my Dead Egg Sperm pattern. It comes out fairly red when you are using it. Don't know if you guy's can get these out there but I'm sure you can get similar pens for writing on Overhead Projector Film.
Some sample pictures of the effect, but really does not do them justice; as seeing the created finished product really does nicely.
This tip was originated by Leon Guthrie of Galashiels, Scotland. You can see his original flies at The Flies of Leon Guthrie.
