I got a new toy today. Last week I took a class at LQS & used this attachment on the machine. It is circular attachment bundle. You sew perfect circles & can sew cording thru a foot as well as ribbon also rickrack. It was so much fun & you can do a lot of different things with it. Funny I was able to buy from Amazon & got it cheaper (half price) than what I could have bought it from dealer. (sad) Can't wait to play with it some more. You can also quilt with it.
