I am trying to figure out how to adjust the tension on my Simple little Singer Sewing Machine. I've been trying to sew 1/2 square blocks. I set the stitch length to 2.5 and the tension setting is a 3 (which is how the machine came). Am using 100% cotton fabric, thread on top and bottom, and have a new quilting needle.
Here's the problem. - The machine has decided to either sew miniscule stitches, or to sew long stitches that don't seem to be locked. (Looks like a long string of thread with an occasional stitch across them) The sewing "bunches up" and I have to hand straighten out every line. I know there is some screw on the bobbin and something extra on top of the machine to adjust tension --- but I am scared to try, because I don't know anything about settings.
Can anyone help with a generic tutorial?
