Give my kids a pack of chalk and they’re set for the day. At least until the last little nub of chalk is finally used up. Which is why it’s so great to know How to Make DIY Sidewalk Chalk! We have just the instructions and it’s probably easier than you think.
To make a batch of your own DIY Sidewalk Chalk you’ll need cardboard rolls first of all. Yes, cardboard rolls. These are your molds.
The rest of the list of supplies include a mix of Plaster of Paris and water. You will also need parchment paper, duct tape, and food colors. Then, the hardest part, waiting for your chalk to set overnight. But you’ll have loads of fun making masterpieces for days to come!

- cardboard rolls – 6 toilet paper size
- 5 cups Plaster of Paris
- 2 ½ cups water
- parchment paper
- duct tape
- food colors
First, tape 2 pieces of duct tape tightly over one end of each cardboard tube. Stand up each tube so the tape side is down and set on a parchment lined baking sheet.
Cut 6 pieces of parchment paper approximately 4”x 6” in size. Roll up each piece of parchment paper and stick one inside a cardboard tube.
In a bowl, mix the plaster of Paris and water until smooth. Divide this mixture between 6 small cups. I used disposable cups. Color each cup of plaster mixture with a different food coloring. Mix well.
Fill each of the cardboard tubes with the colored plaster mixtures. I made mine multiple colors by adding about 3 different colors of mixture to each of my tubes, or you can fill the tubes with a single color. Let these dry overnight.
Tear off the parchment paper and cardboard tubes and you will have 6 large pieces of sidewalk chalk.
One note, because of the food coloring in the chalk, hands may get lightly stained. Just be sure to wash well with soap after use.
This is such a great summer craft for kids to help make and then spend hours of fun making pictures in the driveway! Be sure to find more summer crafts and activities at Our Kid Things and check out our DIY Foam Soap Sidewalk Paint and Kool-Aid Sidewalk Chalk Paint, too!
