Hi All, Would someone have the time to explain the results and consequences of: 1) too tight tension in bobbin 2) too loose tension in bobbin In trying for improvements and educated guesses about what to alter when having problems or not liking the looks of the embroidery I thought this would be good place to start. I'm not talking about extreme tension changes. For example, sometimes I let the bobbin "drop" a little bit looser than other times. Just experimenting, but did not know where to "draw the line".
