Keep me posted. I've experimented with bass tube small nymphs a bit. It's harder to accomplish. You will need to use flat, not woven thread of some kind, so it doesn't cut into the bass tube stuff. And dimple gently.
Wrap a hook tightly with thread. That attach body loosely to the wrapped shank and use glue to make the permanent attachment. ZapAGap, UV glue or water based fabric cement.
