Hi I'm from Alabama, Your so lucky to get fabric that resonable, you asked about your lower bobbin thread, Iv'e noticed on mine a janome.,when that happens its always the bobbin thread , it comes out of the slot on the bobbincase , irethread it and it works fine probably needs adusting.but thats one case i hate to fool with because i have got it out of sinc.... lots of times, so when i get it happy i leave it alone. :D
Have a good week ......memawsaquilting
