I've been known to do the following:
1. Use a hammer to smash a too thick seam- put a board under it, or lay it on the concrete sidewalk. This is an old tailor’s trick and it works very well for places where multiple seams intersect.
2. Flip the seam in question while sewing. This will result in a place where it is “twisted” at some spot. That is easy enogh to manage- make sure the twist is away from a join, somewhere in the mddle between intersections works best, then use some spray starch and a hot iron to flatten the twist.
3. Clip the seam so it can be ironed in the direction you want. When doing this, Just make sure you don’t clip the stitches.
Another possibility: Some folks diagram their pressing plan when designing their quilts in order to avoid the problem- I’ve never done this as I tend to design on the fly.
