Standing double crochet (invisible start)" Explanation: Works just like a regular double crochet (dc) but doesn't leave a visible chain at the start. Technique: Yarn over (like a normal dc). Insert hook into stitch and complete the dc as usual. Pull the starting tail to tighten and eliminate the gap. Used for seamless rounds/rows where you want to avoid a ch-3 gap. Alternative names you might see: "chainless starting dc" or "no-chain dc start." ===================================================
