Tips for FMQing on a 15-91 Please?
I'm FMQing on my 15-91 for the first time and I'm bumping into a few hiccups that I didn't have while FMQing the same quilt on my 'modern' Brother XR3240. For example, my backing is puckering when it never did before. And I'm having quite a time trying to slow my speed down. I have a knee controller. What are everyone's favorite tips or tricks of the trade for FMQing on your vintage machines? I would love to hear them and learn from the wise!
