In this house, craft time is all about reusing old materials. When you have mini muffin tins worn from too much baking, don't toss them! They make a perfect paint pallet. It keeps paint in and colours separate.
Repurposing food that would otherwise go to waste just makes sense. The kids love to use food in new ways. Celery is a great alternative to a paint brush to make unique patterns and with little clean up required.
