✵ How It Works:

Each week, you'll receive a brand-new square pattern straight to your inbox (make sure you're on the mailing list so you never miss a pattern!).

Crochet two squares in complementary colours to practice the technique—and by the end of the week, you’ll have two finished pieces that show off your progress and growing confidence. 🌟

With every new square, your collection grows—adding texture, skill, and beauty to your future blanket. It’s a fun and relaxed way to improve your crochet skills, stay creatively inspired, and craft something truly one-of-a-kind, all at your own pace. ✨

✵ Materials You’ll Need

Yarn Recommendations

Yarn: Worsted weight (#4) yarn is ideal—easy to work with and great for beginners.
Fiber: Go for organic cotton or wool for softness, durability, and crisp stitch definition.
Colours: Use two complementary shades per square for contrast and texture.

Inspiration combos:
🌿 Forest green & cream
❄️ Smoky grey & pale blue
🌼 Yellow & muted lavender

Using two colours really makes your stitches shine!

Yarns to Avoid
Skip slippery yarns like silk blends or super thin lace-weight cotton—they can be tricky to control and might cause frustration. Go for something soft, smooth, and easy to work with.

🧶 Yarn & Hook Tips for This Pattern

Recommended Yarn
Try Lion Brand Basic Stitch Anti-Pilling Yarn in a light color. It’s beginner-friendly, doesn’t split easily, and the stitches show up clearly—perfect for practice. Plus, it holds up well wash after wash.

Best Hook to Use
Start with a G-6 (4mm) hook for worsted weight yarn. Metal or plastic hooks work great for beginners—they help the yarn glide smoothly.

If you're looking for a full set, the Yarniss Crochet Hook Set on Amazon is a great choice. It includes 14 sizes (2mm–10mm), has comfy rubber grips, and smooth aluminum tips to help keep your tension just right.

How To Double Crochet 3 Together (dc3tog) – US Terms

This stitch is a decrease — it turns 3 stitches into 1. You’ll often see it used in textured stitches (like bobbles or clusters) or in shaping.

Instructions (US terms):

1. Yarn over (YO), insert hook into the next stitch, YO again, pull up a loop (3 loops on hook).

2. YO, pull through 2 loops (you now have 2 loops left on hook).

3. YO, insert hook into the next stitch, YO, pull up a loop (4 loops on hook).

4. YO, pull through 2 loops (3 loops remain on hook).

5. YO, insert hook into the next stitch, YO, pull up a loop (5 loops on hook).

6. YO, pull through 2 loops (4 loops remain on hook).

7. YO, pull through all 4 loops on hook.

✨ You’ve now completed a dc3tog – three stitches decreased into one.

📌 UK Terms

• In UK patterns, this exact stitch would be called tr3tog (treble crochet 3 together).

• The method is identical, but instead of starting with a US double crochet, you’re working UK trebles.

Yarn over, insert hook and pull up a loop, yarn over and pull through 2 (leaving one loop on hook); repeat this in the same stitch until you have 4 loops on the hook

Tips for Success with This Crochet Pattern

▶ Keep Your Tension Even

Because you’re working a lot of dc3tog clusters + chain spaces, it’s easy for tension to get tight or loose. Try to keep your chain stitches the same size as your regular stitches—otherwise the square may pull in or look uneven.

▶ . Count Your Stitches Often

At the end of each row, make sure you still have the same number of clusters and chain spaces. Missing one chain or skipping the wrong stitch can throw the whole row off, but catching it early is much easier than ripping back several rows.

▶ Use a Smooth, Light-Coloured Yarn for Practice

When trying this pattern for the first time, choose a smooth yarn (not fuzzy or textured) in a lighter colour. This makes it much easier to see your stitches and spot the chain spaces where the dc3tog clusters go. Once you’re confident, you can switch to any yarn you like
