Trying out some bobbin thread, it is a 60wt, 100 poly (advertised as strong). Using bobbin thread should give a bit better look to the needle stitching.
Did a straight stitch, at machine default settings, and did not notice much of a difference between the stitching. Then did some more a zigzag and some decorative stitching, on the zigzag, again not much difference.
One the decorative stitching, I did notice that the bobbin thread stitching did look a little bit better, overall a slightly cleaner stitch.
Purchased from Ebay 8000yard spool for about $8.00 shipping included. Good price on the thread will use it as bobbin thread on non-stretch fabric.
