One of my favorite things in our sensory room right now is our DIY sequin flip panel on the wall. I made this right before school started by buying a yard of fabric at Joann's and placing it in a large frame I found at Target. I mounted it to the wall in our sensory room with 3M mounting corners, and it has been a big hit with my students! We have a crash pad right underneath the frame, so I have a few students that like to lay on the crash pad and feel the wall.
There are lots of different colors of reversible sequin fabric available, but I bought this one: Glitterbug Reversible Sequins Fabric-Rainbow because it was the only one in stores at Joann's and I was feeling impulsive.
It has been so much fun to play with, I catch myself feeling it whenever I am with students in the sensory room!
