Thank you for the info here. I wasn't sure what was meany by setting the seams. I was also questioning if it matters if you press to one side or if you press open. I like to press my seams open because that is what you do when you sew clothing. I also like that it keeps the seams from being bulky. I pin as I quilt, again because I also sew clothing, so I can match up seams without having to nest the pieces.
