For our Nature Art Area I have lots of great materials that I try to rotate:
- markers — best time to buy these is back to school season 10 pack for $1 at Target or Walmart — we also use these for our *air marker sprayer
- clipboards and golf pencils
- crayon rocks
- natural pencils – I love *these, but I have to sharpen them with a knife (until I can find something better
- pastels
- charcoal
- Paint
- chalk
Plus we are always trying new things.
