I made pumpkin soup for dinner last night and remembered to save the seeds. (None of my kids like the goo, so Daddy had the task of cleaning the pumpkins and the seeds.) After they were dry, I colored them using food coloring and this morning were ready for our art project: mosaics using pumpkin seeds.
Miss M greatly enjoyed this project and made many rainbows, flowers, suns and pumpkins.
I found this idea on Pinterest, but the original idea belongs to Our Little Nature Nest.
