Just recently I was reading on this QB that seams can be pressed open. Due to the new machines,the stitchs r smaller than the older machines etc. This article was just within the last 2-3 Quilting messages. I tried it for the first time and will be doing this from now on. It pressed out nice and flat and easy to put together. I get a lot of information on the Message Board, just need to take the time to read it more often. lol, I hurry up and go look at all the beautiful work done on here.
