I'm still machine quilting this Streak of Lightening vintage quilt as well. It's been a bit tedious because my machine doesn't seem to like the zig zag change of direction. It stitches the first part well and then I've been having trouble with tension. I've made a few adjustments and I'm sewing more slowly which has helped but I'll be happy to finish this one and get on to one which is more co-operative with my machine.
Hugs, Jan Mac
