Hi! I also have a Janome 6600. It is a great little machine, and I love it. It has so many different stitches I don't think I will ever use all of them, but you never know. I too use a wide mouth canning jar to hold my large spools of thread, works great. :-) I get my thread from Marathon Thread, I usually get them at the different quilt shows I go to but they do have a web site you can go to also. I like the Essentials thread form Connecting Threads also but I find it a wee bit linty. :cry:
