They say that skipped stitches can come from a number of things.
Suggestions are: changing the needle, adjusting tension on either top or bottom, changing thread, slowing down your movement when you quilt, or the timing of the machine could be off.
Does it happen the same way all the time? I mean like with the Juki it was always when I was pushing the machine back and to the left or occasionally the right. Since I've heard so many people mention it with the Juki I have to figure it's not just me.
The Hinterberg stretch frame is very sturdy as well. I am very happy with it. I have 10' poles on it but as soon as I have a larger space I'll add on to the poles and make them 12'. I have to find some good instructions to be able to do that.
