Twiddlemuffs are designed for dementia patients to provide tactile stimulation, as well as a method to soothe their agitation. The muffs are great stash busters and are great for any types of yarn. Adding ribbons, buttons, flaps, and ruffles just enhance the tactile qualities of the muffs. Its great to be inventive!
