i have a janome 6260 quilters machine, trying to get the settings on my zig zag right, which i have done lots of time but have been trying for 2 days to get a small zig zag, changing w. and l. tensions , exactly by the book settings, my own settings, different threads, looks o.k. on the wrong side, but not on top, sounds stupid but at my wits end trying to figure it out and it should be so simple!! would appreciate any suggestions, thanks
