What to do if loops appear in the seam of my Brother S-7200C Sewing Machine?
- SSean PerezSep 6, 2025
Loops in the seam may appear if the thread path is not smooth enough or the bobbin is not turning smoothly. Polish the thread path with a fine grain file or sandpaper. Check that there is no slackness in the thread tension by pulling out the lower thread, or replace the bobbin or bobbin case.
