I used to make all of my worry stones at home and then bring them into school. However, last year I had an epiphany and have had the students help make them! The kids love it because they made it themselves so it holds even more value to them. I have also had students in my friendship lunch bunches help me make them this year because they just think it is a fun craft and they get to play with the clay. Some students have really become quite creative with their designs!
I prefer to use Fimo Soft and Soft Effect Clay. I purchase the clay at my local Michael's Store and when it goes on sale for 4 for $5 I stock up. You can even get your teacher discount in addition to the sale price!
Below are step-by-step photo directions to make your own worry stones.
Step 2: Push the clay together to form a ball.
Step 3: Roll and twist the clay in your hand to make a 'snake'.
Step 6: Press your thumb into the ball until you have an indentation that you can rub your thumb in.
Once you have made several worry stones you need to bake them at 230 degrees for 30 minutes. I bake them in foil pans so there is absolutely no clean up.
