I have created Texture Shoe Print necklaces with my Kinder student's for 14 years.
I use stoneware clay and Mayco Stroke and Coat Glaze. I got a few samples of it at the TAEA convention. I like using it for this lesson since you only have to fire one time. I use a straw to poke a hole and I write their names on the back. I use a plastic string so that it doesn't break when they wear it home.
It's a keeper!!
