Yarn Under (YU) is a crochet technique used in amigurumi where the yarn is placed under the hook instead of over. This creates tighter stitches and a unique texture.

How to do it:
1️⃣ Insert the hook into the stitch.
2️⃣ **Bring the yarn under** the hook.
3️⃣ Pull through the stitch.
4️⃣ Complete the stitch as usual.
