How to Make Granny Squares and a Blanket
Crocheting granny squares is a beloved craft with a modern twist on tradition, combining simple stitches with limitless creativity. Whether you are completely new to crochet or seeking a relaxing, colorful project, learning to make granny squares—and to build them into a cozy blanket—is an essential skill that unlocks countless design possibilities. This comprehensive guide covers all you need to get started, from supplies and pattern instructions to assembly, joining methods, and finishing touches.
What is a Granny Square?
Granny squares are classic motifs worked in the round, typically using a series of basic double crochet clusters that create a square shape with open spaces and distinctive corners. Stitched individually and sewn or joined together, granny squares allow crafters to explore endless color combinations and blanket sizes. They are a fantastic way to use up leftover yarn and develop foundational crochet techniques.
Supplies You’ll Need
- Yarn: Medium (#4) worsted weight acrylic yarn is ideal for beginners and durable blankets. Use different colors for a vibrant look or go monochrome for simplicity.
- Crochet Hook: A 5.0 mm (H-8) hook is recommended for most worsted weight yarns, but check the yarn label instructions.
- Yarn Needle: For weaving in loose ends and joining the squares.
- Scissors: Sharp scissors for trimming yarn ends.
- Measuring Tape: Optional, useful for sizing your blanket.
Choosing Yarn Colors
Color selection is where the creativity truly begins! Pick a palette of complementary shades, or use random scraps for a cheerful, patchwork style. For a classic look, try a white or neutral yarn for the border round of each square or a single color for all borders. Planning a color sequence in advance ensures a cohesive final blanket.
How to Crochet a Basic Granny Square
Follow these detailed instructions to crochet a basic granny square. The pattern below uses US crochet terms.
Step 1: Starting Round
- Make a slip knot and chain 4.
- Slip stitch into the first chain to form a ring.
Step 2: First Round
- Chain 3 (counts as first double crochet).
- Double crochet 2 more into the center of the ring.
- Chain 2 (this forms a corner).
- *Double crochet 3 into the ring, chain 2*, repeat * 2 more times (you will have four clusters of three double crochet, separated by four chain-2 spaces).
- Slip stitch to the top of the initial chain 3 to close the round.
Step 3: Second Round
- Slip stitch to the next chain-2 corner space.
- Chain 3 (counts as first double crochet), then double crochet 2 more into the corner space.
- Chain 2, then double crochet 3 more into the same corner space.
- Move to the next corner: *Chain 1, in the next corner space work [3 double crochet, chain 2, 3 double crochet].* Repeat for each corner.
- Chain 1 after each cluster, slip stitch to join at end of round.
Step 4: Additional Rounds
- Continue building out by working clusters of 3 double crochet into each chain-1 space along the sides, and clusters into each corner chain-2 space as before (with chain 2 between the corner clusters).
- Add as many rounds as you like, switching colors each round if desired.
Changing Colors
To change yarn color at the start of a new round, simply finish the previous round, fasten off, and join the new color in any corner space. Continue with the new yarn as above. Weave in all loose ends later for a neat finish.
Tips for Consistent Granny Squares
- Maintain even tension throughout for squares that stack neatly.
- Use the same yarn brand and weight for all squares for size consistency.
- Count clusters and chains in each round to avoid misshapen squares.
- Block your finished squares if needed to ensure they lie flat.
How Many Squares Do You Need?
Decide first how large you want your blanket. Measure one finished square, then determine how many squares you’ll need in each dimension to achieve your target size. For example, for a lap blanket, you might assemble 48 squares arranged in 6 columns by 8 rows. Adjust the number for larger throws or bedspreads.
Arranging Your Squares
- Lay out all completed squares on a flat surface and play with different arrangements.
- Alternate colors for visual balance or create repeating motifs.
- Take a photo of your intended layout to reference when joining squares.
Joining Granny Squares
There are several ways to join granny squares. Choose the technique that suits your style best:
- Sewing with a Yarn Needle: Use a simple whip stitch or mattress stitch. Place two squares right sides together, sew through both loops along the edge and pull gently for a nearly invisible seam.
- Crochet Join: Use single crochet or slip stitch to join squares, working through the outer loops only for a raised, textured effect or through both layers for a flat seam.
- Join-as-you-go: Attach new squares directly to existing ones as you crochet the final round, saving assembly time and creating a seamless look.
Adding a Blanket Border
Finishing your blanket with a border gives it polish and stability. Choose a solid, contrasting color for a classic frame, or work a few rows in stripes. Here is a simple border pattern:
- Attach yarn in any corner stitch with a slip stitch.
- Chain 1, then single crochet around the entire blanket, working 3 single crochet stitches in each corner space to help the blanket lay flat.
- Slip stitch to join the round. Fasten off and weave in the final end.
- Repeat for additional rounds as desired, or experiment with shell or scallop edging for decorative finishes.
Blocking Your Finished Blanket
To help your completed blanket lie flat and showcase the stitch definition, lightly block it by pinning it to shape and steaming or misting with water (if the yarn allows). Let dry completely before use.
Project Tips & Troubleshooting
- Begin with a practice square to get comfortable before starting the full set of blanket squares.
- Keep a yarn needle handy to weave in ends regularly, rather than letting them accumulate.
- For softer, drapier blankets, use a slightly larger hook than the yarn label recommends.
- If your squares curl or ruffle, your tension may be too tight or loose—try adjusting your hook size.
- Don’t worry if not all squares are perfectly identical; minor variations are hidden once joined.
Table: Common Questions and Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Square is not laying flat | Tension is uneven or corners not worked consistently | Adjust hook size, count stitches, block the square |
| Loose joins between squares | Inconsistent stitch type or too loose a seam | Try a different join method; tighten stitches |
| Yarn fraying or splitting | Yarn quality or sharp hook | Use smooth, quality yarn; replace dull hook |
Creative Variations
- Alternate Granny Patterns: Try solid granny squares, striped round edges, or integrate motifs (hearts, sunbursts, etc.).
- Size Variations: Make smaller or larger squares for different effects or combine squares and rectangles for a patchwork look.
- Texture: Introduce different stitch patterns, like popcorn or bobble stitches, on select rounds.
Frequently Asked Questions (FAQs)
Q: What’s the easiest way to weave in the ends?
A: Use a blunt yarn needle and weave the end through several stitches in multiple directions. This helps anchor it securely and reduces the chance of unraveling.
Q: How many yarn colors should I use for my first blanket?
A: Begin with 2–4 colors for a balanced palette. As you gain confidence, increase the number of shades for more variety. Choosing one color for all borders helps unify the look.
Q: Can I make granny squares with cotton yarn?
A: Absolutely. Cotton works well, but your squares will feel denser and less warm than acrylic or wool blends. Always test with your hook and desired yarn.
Q: How do I wash my finished blanket?
A: Most acrylic and cotton yarns are machine washable. Use gentle settings with mild detergent and lay flat or tumble dry low. Always check individual yarn recommendations.
Q: What’s the best join method for durability?
A: For maximum strength and longevity, the mattress stitch or a tight whip stitch with matching yarn is recommended. For decorative seams, crochet joins add texture and color contrast.
