One year I had each parent send items:
Here is an example: I had 20 students so 4 parents brought in:
4 pair of scissors
4 bottles of glue
4 packs of pencils
4 packs of 24 crayons
4 packs of colored pencils
candy and small toys and paper (all parents)
Each students ended up with new supplies, plus they had some candy and toys
In the case that a parent did not bring in something (I just supplied it)...If I remember correctly all parents participated.
It was not a lot of pressure and the kids loved it! and they got new supplies
