Hi we have a blind resident who thoroughly enjoys painting with sponges and also her fingers. She will literally just run her fingers through it. If they are not keen on the paint on their hands you could put a pair of surgical gloves on them. You could also use pasta and paint and glue on a piece of card then they will experience the sensory side of it also.
Thank you for your articles and for providing a place to go for someone with no experience in this field. Without people like you I'd be completely lost! THANK YOU!!!
