So here's my first no-longer-PhD.
Maybe you can't see what it is so I'll tell you. It's a twiddlemuff. And maybe that has left you none the wiser.
It's a double thickness hand muff with bits and bobs attached inside and out. It's designed for people with dementia to have something to occupy their hands and maybe to keep them warm as well.
I've knitted mine using all sorts of bits and pieces of wool from my stash including two very fancy yarn leftovers from knitting scarves. I found a couple of metal keys and some beads from my craft box and I attached those too and a few ribbons finished it off. Everything must be firmly attached so it can't be pulled off easily.
This is mine before I turned half inside and stitched it up so you can see all the attachments.
