"ONLY a 1/4" seam is correct in quilts."
Actually I subscribe to the Mary Ellen Hopkins dictate of "personal private measurement" -- the position my needle is in closest to the 1/4" mark on MY sewing machine. The machines, Berninas 1031, 830, 807, have one needle position slightly less than 1/4" and one position slightly more than 1/4" (among others). I use them both for different purposes.
My quilts are fine and I've never been "fined" for one.
