Hi, I've been building full bodied muppet-like costumes for quite some time now. Recently I've been offered to make costumes a bit inspired on the Muppet's Mutations. Problem is, that these are to be fitted on members of a rockband. So the costume has to be flexibel enough for someone to play a musical instrument, as well as allowing them to see and breathe a good as possible. The flexibility, arms/hands, bodies and feet I already got covered. But my problem is with the head. Does anyone have an idea on how the puppeteers that were the original Muppet Mutations actually saw out this head? Thanks for reading.
