I can see that the roll on the outside is bigger than the one in the harp of the machine. I agree with Patti25314. Try and borrow a machine from a friend. Or, if you were planning on buying one, now is the time. It looks like you have a tad bit more room in the harp of your sewing machine, but just a tad. Really not enough if you are only 1/3 of the way into it. I'm proud of you for quilting your quilt on this long arm table with your sewing machine with such a small harp. Way to go!!! Maybe ask at the LQS if they could loan you one of their extra machines for a couple of days or if you can rent one of their sewing machines with a larger harp. I bet they might! That's if you can't find someone to loan you one.
