Your present settings may not work on different fabrics with different thicknesses. When you start sewing other things, you should do a test run to make sure it's still sewing that way before continuing.
One lesson I did learn is to have test pieces of your work in order to test your tension. As my prevoius posts have stated, I've seen things go wrong. Question: Why does this machine not stitch perfectly straight? Semms the stitches are a little cocked to the side.
Thanks for looking at it.
