First, I extruded some large tubes and let them set up, then I figured three of these 8 inch tall tubes would together become one rack. Then I rolled out a slab to give them "feet" because I felt they needed more stability.
Then I pierced each of the tubes in two places so they can each hold one wire set in a triangular shape. I don't know what this piercing tool is called specifically but it's very sharp and great for hole-making.
Then I scored and slipped the bottom of the tube and the top of the foot and applied the tube to the foot with some pressure.
And there you have it, three tube shaped bead rack holders, currently drying and waiting to be bisqued.
