I have had my HQ 16 an Pro-Stitcher for about 4 years now and finally got around to joining this forum. I was searching for an answer to my bobbin back-lashing. I found several posts about the backlash spring. I have two bobbin cases and never realized that one has the spring in it and the other does not. The previous owner must have removed the spring. Solved that problem! I also found another tip by accident and that was the buttons on the idler pole should be up where they can be seen. Light bulb moment! Mine were down and I never realized that was causing some skipping and hesitation from my machine..........Duh! I always thought my table was the problem. So I just want to say that I think that this site will be extremely valuable to all of us HandiQuilters!
