Optional Hardware

Uxcell is a reasonable quality brand with good prices on Amazon.

Extra Supplies
There are some additional supplies that are useful for some of the lessons. Below is a list of the extra supplies and which lessons use them.
- 3/16 inch White Foam Board
- 20 inch by 30 inch size is a good size. It is easy to handle and can be expanded for larger areas. 24 inch by 36 inch is also a good size.
- If the foam board is warped use wood glue or elmers glue to glue two pieces flat against each other with the warps in the opposite direction and weight down while the glue dries.
- 4mm or 3/16 inch Corrugated Plastic Yard Signs (Coroplast)
- 18 inch by 24 inch standard size. It is easy to handle, can be expanded for larger areas and is more stable than the foam board.
- If the corrugated plastic yard sign is warped use plastic safe adhesive to glue two pieces flat against each other with the warps in the opposite direction and weight down while the glue dries.
- 12 inch x 6 inch x 2 inch Styrofoam Blocks
- Challenge 2"Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come. - 2 Corinthians 5:17"
