Thanks Byron, I often do the same with the green on an adult. I think my use of it comes from the G&H Caddis, which has a dubbing loop of "Arc Chrome" wool pulled under the deer hair body.

The down wing is formed by tying the parachute around a loop of mono, then insert the wing into the mono loop and pull tight. A drop of head cement on the loop helps fix it. Take the tag end of the loop out with a heated bodkin to secure it.

Cheers,
A.
