TheHollerLW Report post Posted December 20, 2018 I am new with this machine, I am having some issues with backside of the stiching and somtimes on the top, other time the top stitch looks great. I am using 210 on the top and 135 in bobbin. Any help is much appreciated! Quote Share this post Link to post Share on other sites
shoepatcher Report post Posted December 21, 2018 I am surprised you can sew #207 the machine. I always believed the max you could sew on a Singer 115W155 was #138 thread. Anyway, the #207 makes adjusting tension on top tough. glenn Quote Share this post Link to post Share on other sites
gottaknow Report post Posted December 21, 2018 This machine will be a lot happier with top thread being T135. Regards, Eric Quote Share this post Link to post Share on other sites
