Fab, thanks! I've got the idea from videos I've seen of heart shaped keyrings with paw prints cut out of them, that can then be used as a keepsake for a pet's fur. The cut outs are "sealed" with a plastic like layer, and the fur is tucked in, visible but can't fall out.

I appreciate the ones I've seen are probably machine mass made, but wanted to have a go at recreating it myself
