Where can I find Amtgard?
Materials
Shield foam: If you are in the Dallas/Ft. worth area: Foam Fabricators Inc. 900 Keller Parkway Keller, TX 76248 (817) 379-6520 foamfabricatorsinc.com
Buzzwords to live by: H-Cell, Laminated Plank, 2 inch, white, density 1.7.
(Laminated is better than non-laminated.
Densities greater than 1.7 are heavier than needed and tend to be too firm.)
When in doubt mention ASTROLAM.
The black foam works just as good, comes in a 4ft x 9ft sheet
