More "What's in Your Supply Closet" items gleaned from recent discussions....
"Gaffers" tape ...extra tough, extra adhesive cloth tape for holding things together and holding them up where duct tape and masking tape simply won't do the job. Gets its name from stage and movie "gaffers" who use it to tape down cords and make quick repairs to scenery and costumes. Comes in many colors. Good for making game lines on the floor too.
White sheets painted with "quick" Bible scenes. Great for dramas and hiding stuff in the room.
Adapter to plug my iPhone into the HDMI slot on our Smart TV so I can show video, photos, and internet content to my class from my phone.
Extra AA and AAA batteries.
