I cut a 6 inch square from a cleanup cloth. The colour in the cloth became so rich after being used many times. I applied fibre paste and pressed a shell slice into it. I added a bit more colour with Inktense pencils. No stitching has been added yet as I am not totally sure that I will add stitch to it. I am definitely leaning towards it though.
