Here's a neat little competition midge pattern tied by our young friend Doug Freemann, that is used widely among the US Youth Fly Fishing Team members, that he tied in front of Tim Flagler's cameras. Its a fairly simple pattern that lacks a tail or any real legs or other parts that stick out, that might slow its descent to the bottom where the fish typically are found in the winter months. If you aren't into comp nymphing, its still a worthwhile pattern fished as you would any other nymph.
Nice job, Doug!
Sharpen your hooks.
