There are many ways to apply dubbing. You can apply it directly to the thread with or without wax, use touch dubbing techniques or you can spin it in a dubbing loop. Semperfli Nymph Dub is intended to make working with dubbing (and your fly tying) simpler and faster. Using Semperfli Nymph Dub is a quick and easy way to lay down a dubbed body on your go-to nymphs. Simply tie on using your thread and wrap the Semperfli Nymph Dub around the hook for a complete body. You can also load the spool into a bobbin for easy handling.
