Sorry the handles did not work for you, but I would think the seller would understand and reimburse you....I am sure you guys could work something out.
I HAVE some Handi-Quilter handles (the kind you used on the original handi quilter...years ago). I used mine with a Juki 1500......if you do some research at your local sewing machine store and find out that they would work for you....I will sell them to you for a REALLY GOOD price
PM me if you are interested or have questions.....
