I'm having tension problems and can not figure out how to correct it. I've tried all I know. I had bought a sit down longarm BabyLock Tiara II. Now I have never had just a longarm before and would do any of my machine quilting on my domestic but did want more room so I could do larger quilts without working so hard to move. I have had this machine for only a couple of weeks and hadn't had much time to use it. But the past couple of days I have been working on a baby quilt. I am having such a problem with the tension. I've checked and made adjustment to the bobbin and the top tension. On the top it looks fine Started out not too bad on the back But then I change the thread. The thread has matching bobbins. But now this is the backside. On the back side flat thread and eyelash stitch. Top side not bad, my quilting sucks, need practice for sure. Back yucky I haven't...
