Thanks for the swift replies!
I was reading that in order to get that perfect seam you have to change the needle position making it impossible to use the straight stitch plate (zig zag plate instead). So it seems like a pain to have to move the needle and change out the plate to get the 1/4 inch seam.
Hoping any quilters with the 9mm machines can chime in! Thanks a bunch ladies (and gents?) ;)
