Many thanks to all who have responded.
I'll be doing some experimenting, indeed!

The project is the largest Audrey II puppet for Little Shop.
I've been doing these puppets for years, and need to make some
refurbishments. Hopefully to keep these in good shape for a while longer
before I have to build new sets!

Any other ideas most certainly appreciated!
