Cross-stitch is a type of embroidery technique that involves creating X-shaped stitches with thread on fabric to form a pattern. Antonyms for cross-stitch could include words like unravel, undo, or dismantle, which all suggest taking apart or destroying something that has been stitched together. Other antonyms might include words like deviate or diverge, which imply moving away from a set pattern or design. Instead of following a prescribed path of stitches, someone who deviates from cross-stitch might create a more free-form or abstract design. Overall, antonyms for cross-stitch suggest breaking apart or moving away from a specific pattern or design, rather than adhering to it.
