Do not know if this would work to stop thread from breaking while FMQ, but this is a tip from a class I took for free motion embroidery. When threading the machine, DO NOT run thread thru that last little clip thing just above the needle. Then of course the tension is adjusted lower. On some machines, there is a screw to turn which adjusts the bobbin tension. These machines have the bobbin system where you have to reach under the machine and the casing that holds the bobbin is removed.That litttle boy will be so happy to see you. Have fun
