My quilting skills are good as long as I stitch in the ditch, or outline, a lot of straight stitching and do very simply meandering. I'm not great at fmq, although I have done some. My plan after looking at this extremely busy quilt is a simple outline of the star blocks. I'll do this with just the batting added to the back of 2'x2' units I've been piecing together. They each have 4 star blocks. I'll add the borders and also do a simple outline. Then, when I add the backing I'll stitch straight lines that cross diagonally across the whole quilt. This is one of the secondary patterns that emerges when it's all pieced together. Because it's so busy I think what I'm planning is enough quilting. But if I had a long arm.....
I can honestly say this gem has been a challenge. Those of you who have gone before me I bow to you!
