I had planned to have a mini tutorial ready today but life has a way of pouring into the day leaving little time for what is planned. I will try for the tutorial by the end of the week but in the mean time there a some scratch beads that are among my personal favourites.
I have simply scratch designs into a veneer of scrap clay over a pre-baked core and then antiqued the surface after baking. As always I sanded with 600 grit, sealed with acrylic floor wax and buffed. Easy to say but it takes a while to put it together as a tut.
