You all have such great ideas and lists. For me, required materials, other than what you've shared are:
1. Fun foam - for everything from headbands, kid-safe spear tips, and more. We even use fun foam for our "Alleluia Butterflies" which we put out to greet parishioners on Easter morning.
2. Michael's large plastic work trays.
3. Paper plates and willow laundry baskets to "hem up" projects of all kinds.
4. Mat board cutter and "self healing" mat for heavy duty trimming.
5. Rotary fabric cutter for making banners to be decorated by the children and costume designing!
6. "Frog" tape!
If I could figure out how to add pictures, I would!!
