My Bernina 830 knots at the beginning and end but I am suppose to be able to override that function but haven't figured it out yet. Drives me nuts. Hate when I have to rip out something...all the knots are hard to rip. I understand you. I haven't tried the twister yet. I bought one, then forgot I bought it and bought another one. Gave the first one away. You are making me want to try it. They look cool!
