This is a quick and easy project that will take approximately 3 hours or less to complete depending on how detailed you want to make it.
We purchased the ½” thick green upholstery foam from Jo-Ann’s Fabric & Crafts for $11 a yard. Use a Jo-Ann's printable coupon from (www.joann.com/coupon) when you purchase the foam and it will only be about $6 a yard. The t-shirts we used are plain light blue cotton Fruit of the Loom t-shirts that can be purchased from Target or Wal-Mart for about $4 each.
Step 1: Materials Needed:
1. The upholstery foam is green ½ thick and “Jo-Ann’s Fabric & Crafts” sells it in 2.5 yard by 24” lengths/sheets (depending on arm length 2.5 yards is enough for a child’s size costume).
2. Low temperature hot glue sticks & gun (regular hot glue may be too hot and melt the foam).
3. A yardstick to use as a straightedge or a fabric cutting board to keep your foam cuts perfectly straight.
4. Two (2) color-matched cotton light blue t-shirts (one to cut/cover the upper foam arms & one to wear).
5. One (1) fine point felt-tip light green “sharpie” permanent marker to draw out your grid lines.
6. One (1) black & at least three (3) shades of green permanent markers or paint pens with large tips (bigger the tips the better) to color in the grid squares on the foam in a random green pattern.
7. Exacto-Knife or box cutter with new blades (dull blades will tear the foam and keep you from getting a clean straight cut).
8. (Optional) two (2) small pieces of black vinyl window screening or black nylon stockings to blackout the eye cut-outs from the inside the head.
