This was the process to get to the tying technique above.
This is the Hawthorn fly as I originally tied it. The abdomen and thorax cover are from one strip of foam, rounded off with a flame, then rolled in your fingers to make it round. If you get it too hot you'll know by the sound you make!

At Charles Jardine's suggestion I changed it to a parachute hackle. Then it sits lower in the surface.

Having got that far I thought that this pattern, Philip White's resting caddis, would benefit from sitting lower in the water, but how to achieve it?

pittendrigh's post on Mothers Day Caddis gave me the kick up the rear I needed to crack the problem.
Cheers,
A.
