AilKat, thanks for the great idea! I have a sleeve ham and also a device that I use for pressing seams that is made like the sleeve ham except that it is longer and roll shaped. That roll will be perfect for pressing open seams. I use it all the time in garment sewing. I can't believe I never thought about using it for quilting. When I press open seams, I use Best Press after I get the seam opened. That holds the pressed edges open. I do not use steam after getting burned a couple of times.
