My biggest learning curve with machine embroidery was to learn how the bobbin tension and the top thread tension work together to make a perfect stitch. I had to learn through trial and error how to tighten and loosen both the bobbin thread and the top thread. After I understood what makes the perfect stitch, whenever I had problems with I could adjust the tension easily to have perfect embroidery. So my tip is to make sure before you leave the dealer with that new machine, have them show you how to adjust both the bobbin and the top thread to loosen or tighten the stitch and to show you what a perfect stitch should look like. This also goes hand-in-hand with stabilizing properly and using the right SHARP needle!
