I made these quick book marks yesterday using scraps of felt and ribbons
Using one skull shape, I sewed on the eyes ,nose and teeth using small straight stitches. I then sewed the two skull pieces together, inserting the bone shapes as I went along until I reached the chin part of the skull where I inserted a length of ribbon then sewed shut.
When I cut my ribbon off to the length that I wanted I dabbed on a tiny bit of clear nail varnish to prevent it from fraying.
I think this skull would also be suitable for making into a nice brooch or hairclip.
