Question about Singer 3343 Mechanical Sewing Machine
SOURCE: Sewing on reverse of fabric
There has to be thread on both sides of the cloth in order to form a stitch.
Refer to the maintenance section of your machine and clean the machine as recommended.
Did you change the thread or needle?
Check the manual to be sure the threading is correct and was done with the presser foot up.
Is the needle is correctly installed?
Check the bobbin to be sure the thread is feeding in the correct direction and through the guides on the side of the bobbin case.

SOURCE: I have a singer 3343c
the presser foot only holds the fabric against the feed dogs in the needle plate area
check the feed dogs to see if there in the up position
if not there should be a nob in the feed dog area to move them up & down
on some models when you remove the extension table the nob is at the back

This seems to be a common problem, but easy to fix. Check the bobbin, and see if the thread feeds out quickly when holding the thread and letting the bobbin case drop. You should see a small screw on the front of the bobbin case for adjustment. Screw that until the drop rate is slight. You may need to adjust a few times to get just the right rate of feed.
Hope this helps, Please rate and comment, Thank You
