What on earth is a twiddle muff?
Well it is also called a sensory band, but that is such a dull name, probably thought up by a committee.
By any name it is a cylindrical band of crochet or knitting with different parts and bits sewn on. It is intended for Alzheimer's patients or others with dementia to hold and fidget or twiddle with. I first saw one on a facebook group I follow. Now I have made 11.
And yes I know that does not add up to 11. I must have missed photoing the one I made first, for my mother.
