Detached Body Pins
Our friend Theo Bakelaar, from Holland, has been tying many imitations of recent days. He is kind enough to send along photo instructions of his very fine work. Some of his imitations call for an extended body, and he uses J:son detached body pins to build it. These are really slick. They are available from Feather Craft in a set of three sizes. See them at https://goo.gl/2zg4uc
Cut thin foam strip.
Mount detached body pin in vise, attach thread.
Fold foam along pin attach with thread. Pull thread up between sides to form rings on body.
Wrap body as long as needed, tie off. Leave butt ends to tie into hook.
Some great example is finished flies using this tool.
