Key facts
Details that prevent common beginner mistakes
Two names, different stitches
US sc is UK dc; US hdc is UK htr; US dc is UK tr. Always determine the terminology used by a source before translating instructions; changing terminology mid-pattern changes the fabric.
Make it easier
- Do not infer terminology only from the designer’s location; use the pattern’s own terminology note.
