I move my needle over, and its different depending on what fabric I'm working with. For example, if I sew two batiks together I don't have to move the needle nearly as much as if I was sewing two heavier Asian prints for example. If I'm using both in the same quilt, I adjust ... and that way my 1/4" is true from fabric to fabric. Its not important when working with larger blocks, but I work quite often with very small blocks and that mis-match of fabric adjustment can make a big difference when piecing 3/4" blocks!
The only bad part about moving my needle is that I can't use the single hole plate.
