I have two ideas for anyone wanting to prototype a shape and field test it before investing more heavily in a durable solution (required) with curb appeal (optional).
1. Use plexiglass in construction of the prototype. Tape on tufts like et al. But lay inside the bed with the camera. A macro lens may be needed though.
2. Use pegboard in construction of the prototype. Again observe from inside the bed. Hold little scraps of paper near different holes to see if air is moving in or out. It should indicate of where pressures are highest and lowest. The grid provides a convenient means to document patterns.
Cheers
