Embroidery question
I have a Pfaff Creative Performance machine and have been embroidering on beach towels (thin nap) for several days. Having an extra bobbin to use when I embroider, I can adjust the tension as necessary. After doing many, many towels successfully, the machine messed up one towel (luckily near the end of my project) and there was no way I could adjust that bobbin to prevent the underneath thread from showing on top! I cleaned out the bobbin area thoroughly, re-threaded the machine, changed the needle and the bobbin thread. I even played with the top tension, which helped somewhat. Nothing seemed to correct the situation fully. Have any of you embroiderers out there
suggestions for me?
