O had started to lose interest in playdough recently, so I revamped her playdough shelf (it's right next to her art shelf). All of the playdough tools and accessories are in the glass jar. The playdough is stored in magnetic glass containers (from IKEA) that hang on a magnetic strip (also from IKEA). She plays with playdough almost everyday, and she plays with putty multiple times per day.
Edit to add: Homemade playdough does not store well in these containers. There is some type of chemical reaction that occurs eating a hole in the metal of the container.
