Reddit reviews Handmade Tiles

You have a good eye for geometric patterns and should look into making ceramic tiles. Couple hundred for a used kiln (make sure the voltage is correct for your house), a hundred or so in clay, plaster, tools and glaze materials and you could churn out lots of tiles pretty cheaply. Going to cover my entire house in handmade tiles someday,they're really fun to make! Try Frank Giorgini's book if it sounds like something you'd be interested in. The world could always use more tile makers!
