When I started quilting, I pressed the blocks open, I read on here, that quite a few pressed to the side, so I started that. Did not like the outcome in the least. Went back to pressing them open. I also came up with a little trick. When joing seams, as I am doing with the log cabin I am now making. I finger press the seams and when joining, just stitching over the opened seam. When I press it's much easier on pressing the rest of the seam open
