Terra cotta clay is a big hit at our house! We used some actual clay (not the stuff we make with flour and water) to make necklaces. The girlies were surprised how hard it was, but once they got it warm in their hands and rolled it out they were having fun. This was great for their dexterity. We cut out circles and used stamps to decorate them. After they were baked, we tied colored string to them and now we wear them proudly! I even made one and I put drops of essential oil on it so the scent can stay with me (I got the idea here).
