Enlarged utensils and T-stools, do it yourself
http://www.instructables.com/id/One-Leg-Therapy-Stool-Autism/ I am tempted to try this! Try making this at your own risk – but T-stools in general are pretty popular with helping fidgety kids focus!
Also, I feel really stupid I didn't ever do this when I did rehab! Basically shelf-liner was used to enlarge these utensils!
