There's a couple of ideas on
Finesse Flytying - Home I was the first tyer in the U.K. to import organza from John Betts in the U.S. back in the early 1980's & shortly after sourced better grades of the sheet material over here.
Back then "ribbons" weren't available though.
My adult damsel on the
Deer Creek - Home page site uses a pearlescent sheet form that's burnt to shape. If anyone wants to try some of the sheet type, send me a stamped s.a.e. The secret of burning it, is to cut it roughly to shape in the jaws of the burner so that you get a 2mm edge to weld evenly all the way around.
