So heres my plan. Glue two layers of foam together. cut shield shape(after making card board stencil) run arm and back straps through slits in desired position. secure straps down with glue and tape.
Now heres the hard part...what should i put on the face before the final foam layer for some added strength?? Will cardboard do it?? Or should i dig out ruts and insert tent poles and glue them down? or do i have to procure money to find plastic? id prefer the most cost efficient method but shoot me what ever works.
