Dena, Rick... great ideas. All I have thought of so far is adding layers of flaps by doing one set and wrapping plastic wrap around them as they dry on the wood, then doing another set right over them. When dry, the plan would be to release one set at a time. I would think you could do quite a layered look that way . There must be a lot more a person could achieve with the hinged mesh technique.... Right now -after reading Dena's post - all I can think of is wanting to make a huge goldfish with flowing thin mesh fins. I wish I was more able to sculpt a fish. Abstract shapes are easier for me (no drawing talent). Laura

Great tip, thanks for sharing, nothing I've tried has worked that great so I will try to remember you "FLAPS"

a lighter alternative I've seen used around here is the wavy fiberglass roofing material (they sell matching wavy trim stuff to make a flush edge that goes against the frame) and rigid (pink foam) insulation.
