Love my Ovation, wouldn't ever buy anything else. There are videos on each of the feet on you tube too. It has a beatiful stitch..I TOO, LOVE THE WAVE STITCH. The auto tension and auto threading is the reason I bought the Ovation. It is so easy to use. Love this machine. The gather foot is incredible, perfect gathers everytime. Be sure to negotiate the full set of feet with your purchase.....àsk what extras they are offering. The feet are more important than the Gold Standard warrañty....etc. THIS IS SERGER PROMOTON MONTH FOR BABYLOCK so you should get a great deal. Enjoy your new Bàby.
