Tartan - Yes, I suppose that makes some difference. I do mostly ruler and FQ and I use Q-nique 15R on longarm, but I'm surely a novice. Did FQ and rulers on my domestic for a few years and managing King quilts that way became a wrestling match. So I splurged.
Somehow I don't like the tiny stitches when I set it for 10 or higher number of stitches per inch. But I'm seeing a trend in the answers here moving toward those higher number of stitches. I hope I'm reading the posts correctly in that these are actual stitches per inch. Some have said "3" and I can't imagine 3 stitches per inch. That's more like basting on my Q-nique. So I'm thinking that is some other gauge. I'll experiment some more before I start my next project on there. I'm wondering if the smaller stitches allow easier FQ without broken or skipped stitches on those curves.
