What to do if my Brother Sewing Machine is skipping stitches?
Skipped stitches on your Brother Sewing Machine can occur for several reasons. Check if the rotary hook tip is missing and replace it if needed. Ensure you're using the correct needle for your fabric; a needle that is too thin can cause this issue.
