In working on my current project, I ran into a seam treatment that just didn't show up well. As I've mentioned once or twice before (LOL!) I use waste canvas to stitch the majority of my crazy quilt seams.
I do not like to pull threads out. I remember doing that so many times with counted cross stitch. Instead, I like to use beads and sequins to make the seam pop or at least show up better.
Using brighter colored beads for a dark background or darker colors for a light background will help to bring attention to a seam that doesn't pop.
It's just a matter of choosing the right colors. You have to experiment. And it's not a perfect fix but if you dislike ripping as much as I do, this is a good alternative.
