I use the bobbin washers! I had trouble with my Janone 6600 making birds nests. Not anymore-they have cured the problem. I was ready to throw this new machine out the window until I changed thread and started using the washers. They weren't any particular size-just generic to everything. I keep them in my travel case too and use them with my Featherweights also.
They're awesome!
