Matthew V! Great video!! Such a nice step by step! You take enough time with each step to make it very easy to follow you! I see that you have several on youtube!
Oh Yeah, and Kraythe, what everyone here has said is spot on. Practice, practice, practice.....cut things apart, watch Matthew's video, try stoneware if you can get your hands on it, if you keep working with the porcelain just remember it is a little more cranky than stoneware, and best of luck, we are cheering you on.
