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.
Golden Carers' website is OUTSTANDING! I tell others about it often. I appreciate everything you do! Your team works hard and it shows! My people LOVE the Rhyming Riddles! They feel so smart when they guess correctly. I repeat them from time to time, and they still enjoy! Feel free to create more.
