Step away from the quilt! Seriously - no one will look at it as closely as you do. I got happier with SIAD when I started not really doing that - my machine has a scallop stitch and I center my foot over the seam and scallop on top of it. A zigzag works for this as well.
I've made over 60 quilts and can't say I'm totally happy with any of them - until I step away!
