Can a design run continuously across a seam?

We print the fabric first and then cut and sew, so a graphic meant to run unbroken across a seam (e.g. body onto sleeve, or front to back over the shoulder) won't line up reliably from piece to piece. There's no seam tolerance in millimetres we could give you that would hold, because the variation comes from the cut and make rather than from the print. Placement inside a single panel is completely free, at any size, with no print window at all, so the design can be moved to sit within a panel.
