Hi Lois - I don't have any really good hints for the seams on this. Since I paper-pieced the blocks, it was a pain wrestling the blocks through the sewing machine as I put everything together. Fabric isn't fluid anymore once you connect it to paper, but I guess that's the point.
I probably would have pressed the seams open if I wasn't worried about light-colored batting showing in the seams next to the black pieces. So I just pressed everything so that all of the intersections nestled together. I'm planning on using a double batting (wool on top of cotton) since this is what I want to experiment with now, so I expect my thick seams will sink into the wool. And my center is busy enough that if I can't stay in the ditch in those areas, it shouldn't be noticable. And everything feels so thin now that I've removed all of the paper! Once I have the final borders on, I'll double-check my intersections and could decide to repress then, clipping seam allowances if necessary. But for now, that's the way it is.
