Wow! This is a great thread! I just finished a quilt that was quilted on my Janome 6600 and 11000. My tension on the back is horrible. I also have the blue dot bobbin case for the 6600. I am so aggrivated that my stitching looks so bad, but it is for me, going on my bed at the lake. I still have to finish the binding and clip some threads. But I will remember the tips given on this thread for future use. I love my Janomes- there has to be a solution!!!
