In straight stitch, which statement is true?

• A. It forms the seam with even stitches on both sides
• B. It links midway between fabric layers, so stitches are the same length on both sides of the fabric
• C. It only works on canvas
• D. It uses decorative thread

Answer: (B)

A straight stitch creates a balanced lockstitch by letting the needle thread and the bobbin thread interlock through the fabric, so the stitch formation sits midway through the fabric thickness. Because the top and bottom threads connect in that same location, the stitch length appears the same on both sides of the fabric. That even, centered interlock is what makes this stitch the standard for seams—strong, neat, and versatile across many fabrics. It isn’t limited to canvas, and it doesn’t require decorative thread.
