There are a few things that we can check first if our machines won't stitch properly before throwing in the piece of fabric and taking the machine into the repair shop.
1. Stitches are loose
If your sewing machine is producing loose stitches this indicates a tension problem. It is best to search your sewing machine instruction book for adjusting the tensions to correct this issue. Can't find your sewing machine manual? The Ultimate Manuals Library is a great resource to check out.
2. Stitch length is erratic
This situation occurs when the feed dog is not at the right height and a presser bar adjustment may also be needed. It is best to refer to your sewing machine manual for the adjustments on your feed dog and / or presser bar.
3. Stitches are ragged
This situation is likely to occur when you're using two different sizes / weights of thread in the upper thread path and the bobbin area. Generally speaking, it is best to use the same thread in the bobbin as on the spool and avoid mixing different threads. Of course, there are exceptions to this rule such as when you're doing machine shirring or embroidery.
4. Thread loops on bottom
When your thread loops on the bottom it can indicate one of two problems. First thing to check out is your sewing machine needle. If the point of the needle is blunt that could be your problem and it's easily fixed by changing the needle. If you checked and change the needle and are still experiencing the issue, it could be the tension. Refer to number one.
5. Frayed stitches
When frayed stitching occurs this indicates that the machine needs to be cleaned of all the lint in the lower bobbin assembly area.
6. Zig-zag stitches are uneven
Uneven zig-zag stitches again indicates a tension issue that needs to be addressed. Refer to number one and check your sewing machine manual for these adjustments.
