What is the correct order of threading colors for the Serger sewing machine to prevent unraveling?

• A. Red, Blue, Green
• B. Blue, Red, Green
• C. Green, Blue, Red
• D. Blue, Green, Red

Answer: (B)

The correct order is Blue, Red, Green. Threading in this sequence sets up the interlocking path so the stitches lock onto each other and the fabric edge, which prevents unraveling. Blue goes first to form the base chain along the seam edge. Red is threaded next to interlock with Blue, building the main overlock stitch that wraps the edge. Green completes the loop, locking everything in place. If the order is changed, the final thread may fail to capture the others, leaving the edge more prone to unraveling. Always follow the machine’s color-guided threading path and test on scrap fabric to confirm the stitch locks correctly.
