Gorilla Glue: $7
Wood Filler: $11
Mod Podge (Matte Finish): $8
All-purpose Chipboard: $1.36 - $3.42 per sheet (I would suggest having 3 14-ply 28”x44” sheets and 1 30-ply 28”x44”. This is if you’re making the shield only)
For the foam, you’d have to go to your own hardware store to pick it up. Think like this one I’ve found. I had them cut it in half for me so it was easier to carry since this one is 8ft tall. It’s 2in thick so that gives room to play with.
Box cutter: $5 (+ a few extra dollars for extra blades. You’ll need to change them often)
Silver Spray paint: $8
