hiya! i shall try and explain myself so that i am understood; please bear with me! i have a janome 2010, and i can sew all day long and not have a problem. but when i 'attempt' (yes, still learning here) to fmq, it starts great, but when i change the bobbin, or sometimes when the bobbin thread gets low, i can hear a little 'pop' and i have wads and balls of loopies on the underside of the fabric, while the top looks just great. i have thought it might be the bobbin tension, but the tension is great with everything else, either with sewing just thru 2 layers, or when batting is added as well. it seems if i play with the bobbin after a bit then it will be okay on scrap, and i can take off again until the bobbin is empty, then we start this long process all over again. am i just a dork? the machine has less than 100 hours on it and is always lint free with new needles and not a speck of dust anywhere. has anyone else had this problem and if so what did you do to change it?? if i'm a dork its okay to tell me so, its the only way i will learn!! i live pretty remotely and really dont have a network of sewer friends to give me a hand here. thanks much!
