Welcome to the latest installment of our series of videos called “One-Minute Fly-Tying Tips and Techniques” from Tim Flagler of Tightline Productions. Each video will teach a single tying skill, from the most basic to the advanced. Ultimately, the series will serve as a sort of encyclopedia of tying skills that will be a valuable resource for anyone who sits down at a vise to create a fly.
Most tiers don’t sit down to tie a single fly; instead, they usually aim to crank out a few of the same pattern. If you’re using head cement, it need a few minutes to dry, but you don’t want to have to wait before you start on the next fly. Tim offers a simple solution, and as usual, he’s thought of everything–including how to ensure that the cup doesn’t tip over with all that weight at the top.

Save time by applying head cement to all of the flies at one time after they have been placed in the cup.
I have not used head cement in years and have not had any problems with flies unraveling.
So there is always that option ; )
For large saltwater flies cut “pucks” out a foam pool noodle.
