The straight line quilting looks fantastic on that quilt! And your placemat is really cute, I have yet to try Quilt as you go. So you're not a chicken, you just do what works for you!
I love your version of this quilt, Diana, especially how you've stopped the flipped strip short of the ends.
Nothing wrong with straight line stitching. I really like the colors of your placemat!
I'm a big fan of straight line quilting! Really suits the strip quilt!
