The teacher next door had her students all make meditation beads from polymer clay and they were gorgeous; I will have to ask her how they did it. In Montessori you always have a Peace table in the classroom, so we already have a Buddha statue set up with meditation beads. We also all have yoga mats at school so that we can practice yoga.
