📚 What you’ll learn

How yarn thickness and hook size affect stitch size, texture, and tension.

🎥 Watch

📋 Instructions

  1. Follow your pattern if applicable — start with the recommended yarn weight and hook size.
  2. Check your yarn label for suggested hook size.
  3. Look up the yarn on the Craft Yarn Council website to confirm weight and hook.

  5. Fine-tune your hook selection based on comfort, tension, and gauge.

🔑 Key tips

  • Medium-weight yarn (#4) and 5-5.5mm hooks are good starting points.
  • Too tight → go up a hook size. Too loose → go down.
  • Ensure yarn slides smoothly under the hook taper.

🏋️ Practice

  • Take a few different yarns (e.g., light, medium, bulky) and a few different hook sizes.
  • Loop the yarn over the hook and gently pull or tug to feel how it slides. Notice how the yarn sits on each hook — does it feel loose, tight, or just right?
  • Compare the feel between yarns and hooks to develop an intuition for tension and stitch size.

🎯 Goal

You can recognize how different yarn weights and hook sizes interact and get a sense of comfortable tension before starting actual stitches.
