What do you do with the large spools? I have a Janome 6600 and a Janome 6500. I tried to use the BL by putting the cones on the table right behind the machine and running the thread up through the tall thread holder. I had constant breaks with both 80 large eye and 90 large eye needles. I've given up trying to use it on top.
At first I though it was the machine, but I can FM with Aurifil 50wt. and Polylite with NO problems. The Aurifil and Polylite are on spools which I put on the thread pins, but the BL is a large cone. I'm wondering if where I put the cone has something to do with the breaks. I've done sitd with spool BL and didn't have any problem.
So, if you use the BL cones, where do you put them?
