E. Helpful Hints
1. If your sewing appears as shown on drawing,
stitches on top side of fabric are good but bottom
side tends to look like a towel, it could be that the
upper thread is not threaded correctly. Refer to
page 32 for correct threading.
2. If after checking the top thread and the bobbin
thread is still showing on the top side, check the
bobbin to see if it is set correctly. Refer to page
30 for the correct setting.
