Yes you are right on this. If it is causing problems on the bottom of the quilt the first thing I do is check to see if it out of the up take lever. If on the top of the quilt make sure your thread in the bobbin is through the tension. Rethreading both sometimes take care of the problem. Always thread your machine with the pressure foot up or your thread will not lay in the tensions right. (When the foot is down it closes the upper tensions)

First, what machine are you using? If it is a midarm, mine does not have a presser foot to lower. I was told to start with my bobbin tension. Once I had it just right, and as long as I do not change thread weight it stays fine.

1st. what machine
2nd size of needle
3rd thread, type and size
4th tension on quilt sandwich, ( I take it, it is on a frame)

I have the Gracie II frame and a baby lock Quilters Choice Professional machine that came with it.

I use #16 sharp needles

Thread is guttermans (sp?)

I have rethreaded the machine a million times with needle up and have been putting my pressure foot down each time.

Trying hard not to give up----seems worth it now to send the quilts out-but how long can the learning curve go on?

Start from scratch. Make sure there is no dust or lint in the bobbin casing or the machine. Make sure the needle is in right and the presser foot goes all the way down. Then re-thread. But wait till tomorrow when you are fresh.

If all is threaded correctly -then you need to tighten the top tension

I'm glad it's not just me having this problem. Seems every day the tension adjusts itself overnight. Some little gremlin comes to mess up my life!! Maybe it's the room temp. or atmospheric pressure. I too have started to ask myself why I ever bought a machine instead of paying someone else to quilt for me.

Not sure what system you are using, but once I set my bobbin tension, it is all the top that needs adjustment. If you see top thread on the bottom, tighten the top. If the bobbin thread is poking through on the top, loosen the top tension.
