Who wouldn't want an extra brain at Christmas time? You could have one spare just in case the other one gets too drunk or forgets where the presents are hidden.
I have a friend with a PhD in psychology, what would be more apt to hang from her Christmas tree than a brain! I set to work, using felt, metallic thread, stuffing, ribbon, a little bell and an old physiology textbook that I had at university - I knew it would come in handy one day!
I cut out a brain shape in pink felt (including the important brain stem!) and stitched it on to a green felt circle.
I then stitched the texture of the brain, including lots of folds and crevices.
Then I joined this on to another green felt disk, using back stitch around the edge. Before sealing up completely I stuffed, and added hanging ribbon and a little bell. Now the brain is finished. Hang on your tree to give you extra brain power this Christmas!
