Homemade Sidewalk Chalk


Remember that Plaster of Paris project?  I had originally bought that plaster of paris two years ago to make homemade sidewalk chalk.  Well, now, two years later, I've finally done it!!  Most recipes that I've seen call for:
  •  1 cup  plaster of paris
  •  3/4 - 1 cup of water
  •   dry tempera paint
  The craft store that I shop at does not carry the dry tempera paint any more, so I just used some liquid tempera paint.  We mixed the paint in with the water first.  Then we added the plaster of paris and mixed until it was all combined.
 Then, we poured it into the molds.  We used Candy Molds.
This amount filled 3 candy molds and 3/4 of a toilet paper tube, so about 12 pieces.
  And then, we let it dry.  It took ours about 3 days to dry enough so that they wouldn't crumble when we tried to get them out of the molds. (This is a be-patient project!)  I don't know if the quikset plaster of paris would have dried a lot quicker, but our store also doesn't carry that anymore!!  I think that 1 cup of water was actually a little too much and with the liquid paint instead of the dry paint, it could maybe even use a little less than 3/4 cup of water.   And I think the molds were a little too shallow.  I would have liked them to be a little bit thicker.  I used a toilet paper tube taped on the bottom also, which is what the chalk in the bottom left corner is.
  I loooove the way it wrote on the driveway.  It felt so smooth!     And it's very inexpensive to make.  I believe the Plaster of Paris was between $4 and $5.  It came as a dry powder in a half-gallon container.  My 1 cup that I used barely even put a dent in the container, so I'll be making a lot more chalk.

I also saw this idea for Sidewalk Paint  from Nicole at "Plain Graces".  Very cool idea!  Check it out!

  I had never thought of Sidewalk paint before!  Very clever.
