Hi Listers, Saw this on Home Matters (Discovery Channel) today. It's just right for us, broader and longer than the standard sold for children's use. Tempera paint is washable and used by young children. It can probably be found in craft stores and five and dimes (Really!). --------------------- Sidewalk Chalk 2 C. Water 2 C. Plaster of Paris 2 Tbl Tempera Paint (Wet or Dry) Toilet Paper Tubes with duct tape over one end Combine and stir together. Let stand a few minutes. Place tubes on cookie sheet lined with foil or wax paper. Pour mixture into holders, let stand until semi-firm. Remove holders and let dry completely - ready to use in about 1 to 1 1/2 hrs. (reminder, never pour plaster down sink). Dick McCracken Towanda, PA -- Plan Your Work... Work Your Plan...
