jk215 Report post Posted November 9, 2015 I make a product (notebook case) that requires me to sew from 1 to 3 layers depending on what part of the design I am at. Usually the 2 and 3 layer sections stay pretty uniform but obviously the tension isnt right when it gets to the part where there is only 1 layer. Is it common to adjust upper thread tension while sewing to accommodate problem spots? Quote Share this post Link to post Share on other sites
mlapaglia Report post Posted November 9, 2015 Im not sure its common but I do it. I make a test run on some scrap from the project and make note of the tension settings. Then as I transition I make adjustments. FYI I use a Boss. Im not sure it would work on an electric machine. Quote Share this post Link to post Share on other sites
