First, we have a new sensory table in our kitchen! I know my son will NOT be neat and tidy with any sort of sensory activity and I didn't want to always be getting something out and putting it away. I wanted a dedicated spot to store a sensory bin and our light table. An area that he could go to let me know he wanted to do these sorts of activities. My son has a speech delay so he cannot verbally communicate what he wants yet. This works out well, because he can pull me over and point to what he wants to do. The sensory "corner" simply consists of an old end table that has lived in almost every place I've lived in my life (it was in my mom's house when I was growing up and I took it with me when I moved out). A rubbermaid container holds the sensory bin materials and can be stored underneath the table. Our light table can fit on the shelf below the tabletop and the bin on top of the light table contains the messy play. The materials we use on the light table are stored in a separate cupboard.
Just as a quick sidenote....I also cut up pipe cleaners and emptied an old parmesan cheese container so he could work on fine motor skills by putting the pipe cleaners in the container.
