I bought a longarm Tin Lizzie 18, but I'm having all kinds of problems. I don't know if I have it set up wrong or what! My thread keeps breaking and now I can't turn the knob on the upper tention. Also if anyone know someone in central Kansas that will teach me how to use my longarm could you please let me know. I bought it in April and have only quilted a table topper that was 36" x 36". I have a quilt on it now but I've had to stop several times and i'm on the 4th row of edge to edge quilting. Maybe someone know a good on line video to help? I've done a search and watch as many as I can on youtube. Thanks in advance.
