In canopy repair, which statement best compares lockstitch and running stitch?

• A. Lockstitch provides a secure seam with a locked end; running stitch is a continuous stitch that may require finishing.
• B. Running stitch is more durable than lockstitch.
• C. Lockstitch cannot be undone.
• D. Running stitch creates the most secure seam.

Answer: (A)

Understanding seam security and end stopping is key in canopy repair. Lockstitch uses two interlocking threads from the needle and bobbin, so the stitch can be locked at the start and end with backstitching. That creates a secure seam whose ends are fixed, which is ideal for canopies that must withstand loads and movement. Running stitch, by contrast, is a simple straight stitch that doesn’t interlock; without a locking finish, it can unravel along the seam, so you typically finish it by tying off or backstitching to prevent movement. Because of this difference, lockstitch with proper locking is the more secure choice for canopy seams, whereas running stitch is less secure unless carefully finished. The idea that running stitch is more durable, that a lockstitch cannot be undone, or that running stitch creates the most secure seam, does not fit how these stitches behave in practice.
