Get yourself a drawing tablet and start doodling. I have multiple tablets going with different patterns. I do them in DIFFERENT scales (small - medium - large). My first attempt focused on loops and loops with alternates (hearts, leafs, double-loops, etc). The more you draw these patterns and repeat them, the more you are creating muscle memory. When you start quilting the same pattern, your body will remember how to do it because you practiced on paper. Then keep trying different patterns. It really works!
