Pantograph spacing question
I now have a mid-arm machine on a frame (yeah!) and am ready to try out pantographs. I've found videos on their use as to correct placement of the rows, but nothing that deals with the spacing on a quilt to make sure you don't end up with just a few inches. Not sure I'm asking this right. The one I am currently using is a 6" wide, but my quilt is 68", which isn't evenly divisible by 6. So I'd end up with 6 - 1/3 rows. Not good. How do I make the adjustments between the rows to come out even? I'm hoping there's a nifty calculator or something to do this.
