I have never wrapped furry foam around a shank. The FuzzyDragon (T. Muncy) utilizes Furry Foam as a backstrap over the abdomen/thorax. But, here the tyer wound the material for the body. Some nice flies at this site too; click on the pic to enlarge.

never thought of that before. thanks for passing this along. Looks like a great way to get an evenly formed body.

I had not seen it before either….I wonder if the foam would need to be adhered to the shank with head cement or a ribbing to avoid shifting…maybe not even an issue….unique use of the foam.

Looks like a good material for caddis larva.
