Male house Sparrow bauble
using polymer clay as Scratchboard...finally got down an idea thats been sitting on the shelf in my head for far too long. just about any item you can cover with polymer clay could be fair game for this tecnique and you could easily use a differant colour marker or clay
i covered a plain glass bauble in white polymer clay then baked and sanded. since i didnt need a buffed surface i used 400 grit followed by 600 grit sandpaper just to get the bumps out, then i covered it with permenant marker (buff and rub with your fingers (or a rough cloth if you are leaving the house the same day as this will stain your fingers a rather fetching black/blue colour) to remove 'scribble' marks.
depending on the brand of marker you may need two coats. i used a CD marker
i then scrapped the design using a craft knife and a thick needle. you can trace the design onto the bauble or draw it first with a pencil first.
finish with a coat of varnish.
im quite pleased with how this turned out especially since ive never tried scratchboard before
