Instructions for making your own clay out of sawdust.
2 Cup Sawdust
1 Cup Dry Wallpaper Paste
Blend the sawdust and the dry wallpaper paste together. Slowly add the
water and stir until your mixture is a clay consistantly. Once you have
your clay made you can make shapes, designs, creatures - whatever you
want! Let your creations dry atleast 24 hours. Once they are dry you can
sand them and paint them!
