We used black construction paper, and put the paper snowflakes underneath. Then, she used the side of a white crayon to make the rubbing. She thought they looked like snowflakes at night!
Clara gave it a try too! I used masking tape to keep the paper from sliding around on her high chair tray. I think the girls liked seeing when their snowflakes started to appear on the page... it's like magic!
Clara wanted to do more of these, so we offered her white paper and a blue crayon the next time. She was having so much fun!
A good tutorial on paper snowflakes can be found here. Have fun!
