Red holographic tinsel adds a touch of sparkle to this otherwise sombre pattern. Attach the tinsel strands convex side in so that they hug the Fritz.
Using ‘small’ 5mm foam dowel for the eyes ensures the fly’s rate of ascent is slow enough that it can be held on the hang for a few extra seconds, even when the fly line has been fully retrieved.
Ultra thin, ultra strong threads don’t really work on this pattern as they would easily cut through the soft foam dowel. Consider a 140 denier thread which won’t cut the foam but is strong enough to hold it securely.
When forming the eyes make sure they are evenly-sized. If one eye is obviously larger than the other the Booby will not fish on an even keel as intended.
If you need to trim the eyes so they are the same size and a nice round shape use a sharp pair of finetipped scissors. It’s easier if you remove the hook from the vice to do this.
