From Misty Cut tube from bottom into three 'rings'. Use them for egg stands to decorate Easter eggs and display. Let dry and it will have a leathery look to it. A guy in our home town had me save them once for him. He used the jars to store his homemade horseradish sauce and jellies.
Kids can sort money in the jars.
I buy paints in large gallon size, so when the preschool kids are ready to paint I pour a little into baby food jars. Then when the school kids come home, I let them use the leftover paint that's in the jars or I just put the covers back on and save it for next time. The kids made bath beads for a gift for Mom at Mother's Day. We poured the beads into babyfood jars, added a ribbon and it made a wonderful gift. Add wiggle eyes and a frown to complete it.
