Do something 1300 times, and you will definitely do it differently at the end than at the beginning. I just picked up a brick from my very first batch in July 2012 and compared it with the last batch I made a couple weeks ago. The difference in quality is amazing.
I learned, as I was making, how best to scrape the mold so the edge stayed crisp. I learned how to use sand sparingly but effectively to keep the clay from sticking. I learned not to put so much sand in the mix, because the less sand, the stronger the brick. I learned to pack the mold so that the sides come out smooth and even. The latest bricks are still not perfect, but they are many times better than before.
