One topic that came up was how to do the "rocking stitch." The needle goes straight down, then rocks back up through all layers, then straight down again. Really, not that easy at first. I've tried.
Another quilter decided she must be doing a "running stitch"
because her needle was more at an angle when it entered the layers.
She tried the "rocking stitch."
Who knew you could learn so much from a small group?
