Well, the call of the wild and wonderful Horizon was temporarily the sound of a cough. Give it an easy border or two to sew-no problem. Give it a bunch of pieces to sew together to make a block and the stitch tension was impeccable. BUT ASK IT TO FREE MOTION MACHINE QUILT and look out! How many times did I start and stop abruptly to the error message E7-Not the dreaded E7!!! you say, yes, it was E7! Return to the dealer the circuits are incorrect, or something to that effect. In other words I really messed it up. And did the only sane thing to be done in this event, I turned it off and turned it on and began again.
Well, not be dumped on by any sewing machine, let alone the Horizon, I soldered on began playing with the tension button, and changing the 3 feet that are given for the free motion machine quilting. And there was the answer, CHANGE THE FOOT! and play a little with the tension and slow down the machine a little and there it is a pretty darn good stitch.
The 200.00 Brother or the 3,000.00 Horizon, both are a finely tuned machine and even the slightest thing out of balance can cause your stitches to look funny. It's almost always a simple change of the needle, wind a new bobbin, or rethread your machine and you will find the answer to your bad tension.
