I used slab building for this tube project. Step 1: I wrapped a cardboard tube with newspaper and taped it. Step 2: Gather some clay, wedge and flatten it, then roll the clay through the slab roller. Step 3: Make and use a template to cut out the slab piece. Step 4: Roll the clay onto the card board tube, cut any excess clay off. Step 5: Score the clay and smooth it out with a smoothed edge scraper. Step 6: Smooth, measure, cute and remove tube.
My artmaking skills have improved. I have become more patient with my work, making it more smooth and even.
