I have a Tin Lizzie 18 and use my stich regulater all the time. I find when not using it I can't keep my stiches even. Because I do not move at a steady speed, I find myself going slower in the more detailed or smaller areas of my designs, then I will move faster in the larger loops, feathers ect. I do all free hand LA. Sometimes I have to stop for a second to change direction or think about my next move, with the stich regulater the needle stops moving when I stop. I keep trying to use the regular setting but I'm just not comfortable with it yet.
