I think I’ve finally learned that when I’m having problems quilting to walk away for a while (or a night) and try again at a later time. I had to re-thread my longarm yesterday evening after my thread broke – some freaky thing on the cone got caught up. For some reason I could NOT get the tension readjusted so I could get back to quilting. After making several adjustments that didn’t help I shut down for the night.
This afternoon, I walked back in the room, unthreaded the machine and started from scratch – a quick tweak of the tension dial and I was back in business.
