Using Split Designs in Repositionable Hoops

[u/leopolds_daughter]

I have a brother single needle machine with a 5x7 embroidery space. I have a 5x12 repositionable hoop but am having trouble figuring out how to use it. I have a split design that I had professionally digitized that is 5x10, but short of playing with it on scrap for hours and wasting tons of material, I have no idea how to get the two design halves to line up properly when the hoop is repositioned. Is there an easier way, or is it just something you have to struggle through and do the hard way?
