Yes my granddaughter is a occupational therapist (not sure about my spelling) she uses these and she says they really help. We made them about 12 or 14 inches square. Cut two pieces of colorful fabric. She said even cords or fabric with heavy weave would work we sewed seams about 1 to 1 and half inches apart across the two pieces of fabric and filled them. Then enclosed the ends some we made filling with a special filling we found at Walmart than we made some filling with rice. She did not believe we would be able to wash the ones fillled with rice. But she needed so many in her job that we were being economical. I am sure you can goggle and find out more.
