I haven't used my sewing machine in 5 years. I got it out and I'm all ready to sew but I get this massive thread knot(??) on the bottom of the fabric from the bobbin part. The thread gets all tangled up in the bobbin compartment. I have no idea what the real names are for the sewing machine parts...other than needle and foot pedal!

LOL Any ideas why this keeps happening?

Please help before I lose my courage!!
