Continuous designs work best in a continuous hoop. But - if you have digitizing software, add jump stitches to the end of the design going side to side and line up on those. The side to side stitches need to be at the start and finish to make sure the needle lines up on the swing. I have a Pfaff 2144 and saw how they lined up the designs I got with the hoop. I prefer Babylock's Designers Gallery, and have added the same type jump stitches on everything I have split, including the Grand Hoop. Pfaff has precise positioning, but it's no good if you can't see WHAT you are positioning on.
The Continuous Hoop for the Pfaff is 100x120? (can't remember length) So you can use any design that is less that 100mm wide. I've hooked edging with eyelets together for finishing heirloom nightgowns.
The continuous hoop releases so you can pull the fabric up in length without rehooping.
You could also mark the end stitches with an air erasable pen - just side to side as the jump stitch. People used to do whole jacket backs with a 4x4 hoop.
