I am a presser too.From each individual seam to the loading on the longarm. When paperpiecing I also have the mini iron to press those seams with. To me they lay so much better and very seldmom have to block for size. When quilting on the long arm Every top and back will get a press before loading(they lay so much nicer aven tho they get a touch of stretch) One of the first quilts I quilted I had not and when it came off the long arm you could still see the fold down the center.From the point on I press one and all and everything in between.
