I'm pretty happy with how exact I've been able to get the quilting lines. Want to know how I do it?
Since the tape is an inch wide, you just stick it to your quilt face in adjoining strips. Then, you sew in between the strips.
I actually finished this stage of the Name-That-Quilt quilting today. The question I'm mulling over now is whether I want to do more quilting on it -- maybe even go in-between those one-inch lines to make concentric shapes 1/2 inch apart -- or whether this much is good.
(In fact, I did more quilting today than any other day, ever. I decided last week that today was going to be breakfast-to-bedtime quilting -- The Quilting Death March, I've been calling it, with my usual impeccable good taste -- and it turns out that you can get a hell of a lot done when you throw a whole day at it. I'll show you what I've been up to in a progress report next weekend.)
