I think you'd love the Sweet 16. Also, ask about pano's and rulers. Maybe you can copy the pano's onto lighter weight paper and then sew through. I would wonder if there were a way to use the rulers, so they wouldn't slip.
Years ago I saw a 'cradle' that you could use with any sit down machine. If I can figure out how and when to download my picture files onto this new laptop I'll have a picture to show.
