I'm practicing FMQ , and am getting large needle holes in the fabric. I'm using a 90/14 needle. Also, sometimes the holes are in the fabric but the stitches aren't being made. I rethreaded the machine, put in a full bobbin and put in a new needle. I'm certain someone is going to mention tension. How can I tell if the tension is right or not? On a positive note, the practice I did drawing has paid off. I'm very pleased with the designs I'm making.
