What Makes a Granny Square “Unusual”?

The traditional granny square is a four-cornered square worked in the round, usually starting with a small ring and building outward with clusters of double crochets and chain spaces. It’s a timeless design — but it’s just the starting point.

An unusual granny square breaks from convention in one or more of these ways:

  • Shape — The motif inside the square is figurative, like a butterfly, skull, star, or moon
  • Structure — The square itself may be non-square, like a hexagon or triangle base used to build into a square
  • Texture — Special stitches like back post double crochet (BPDC), front post double crochet (FPDC), bobble stitches, or popcorn stitches add raised, dimensional texture
  • Color — Strategic color placement creates diagonal patterns, gradient effects, or multi-corner coloring within a basic square
  • Center — Instead of a traditional round or cluster center, the motif features unique circle designs or lace-like openings

The beauty of these unusual patterns is that they still work up into squares you can join into blankets, bags, clothing, and more — they just look dramatically different once stitched together.

Getting Started: What You Need

Before diving into the pattern roundup, here’s what you’ll typically need for granny square projects:

  • Yarn: Worsted weight (size 4) is the most common and beginner-friendly. For finer details in figural squares, sport or DK weight can give sharper definition.
  • Hook: A 5.0mm (H) hook works well for most worsted-weight patterns. For tighter-textured squares, try a 4.5mm (G).
  • Scissors and yarn needle: For fastening off and weaving in ends (there will be many with colorwork squares!)
  • Stitch markers: Helpful when working the joining rounds of unusual shapes
  • Blocking mats and pins: Essential for getting those squares to lie flat, especially with 3D or figural designs

Now let’s get into the patterns.

1. Unusual Geometric Shape Granny Squares

This category is where things start to get really interesting. These patterns require you to crochet a recognizable shape first — a butterfly, a star, a skull — and then incorporate it into a square frame. The contrast between the detailed motif and the surrounding square background is what gives these designs their striking visual impact.

Butterfly Granny Square

The butterfly granny square is one of the most beloved in the “unusual shapes” category, and for good reason. Using a contrasting color combination — think cream wings against a deep navy background, or pastel pink on sage green — the butterfly motif pops beautifully.

Key tip: Use a hook one size smaller than recommended when forming the butterfly shape itself. This helps define the wings and keeps them from splaying outward as you build the surrounding square.

The butterfly works especially well for spring and summer projects: baby blankets, tote bags, and children’s sweaters. You can find the free Butterfly Granny Square Pattern here.

Rainbow Granny Square

Rainbow shapes carry so much positive energy, and this pattern channels all of it. The arc of the rainbow sits against the square background, worked in the traditional ROY G BIV color order or in any color palette you love.

This is a fantastic pattern for scrap yarn use — raid your stash for all those partial skeins. Get the free Rainbow Granny Square Pattern here.

Moon and Sun Granny Squares

Celestial motifs are having a major moment in the crochet world, and these squares are a gorgeous way to tap into that trend. The collection includes four distinct designs:

  • Sun and Cloud Granny Square — A cheerful daytime scene. The fluffy cloud shapes are created with raised stitches. Moderate difficulty.
  • Sun and Moon Granny Square — A more advanced design combining both celestial bodies in a single square. Striking in yellow and midnight blue. Advanced difficulty.
  • Moon Granny Square — A crescent moon worked as an appliqué-style motif set against a dark background. Moderate difficulty.
  • Sun Granny Square — A radiating sun design with defined rays. Works beautifully in golden yellows and warm oranges. Moderate difficulty.

Mixed together or used individually, these four squares can create a stunning celestial-themed blanket.

Star-Shaped Granny Squares

Stars are probably the most popular unusual granny square category, and the variety available proves why. There are currently six distinct star patterns, ranging from simple 5-point designs to elaborate starburst textures:

Working through all nine of these star variations would make an incredible sampler blanket on its own.

Poker Suit Granny Squares

Here’s an unexpected category that’s incredibly fun to work with: playing card suits. Spades, hearts, diamonds, and clubs, each embedded in a granny square background.

A four-square set makes an excellent coaster set, and a full deck’s worth of squares (repeated across a blanket) would be absolutely show-stopping.

2. Skull and Halloween Granny Squares

Few things in the crochet world are as immediately eye-catching as a skull granny square. This collection has grown into one of the most extensive unusual granny square libraries online, with nine different skull designs ranging from easy to advanced.

The Skull Granny Square Collection

These squares are ideal for adult sweaters, bags, wall hangings, and of course, Halloween-themed blankets and throws.

Other Halloween-Themed Granny Squares

Beyond skulls, there are several more Halloween-ready unusual patterns:

  • Spider Web Granny Square — An intricate web design, beautiful in black with a white web or vice versa. Moderate.
  • Ghost Granny Square — A friendly ghost shape surrounded by a square frame. Advanced.
  • Cat Granny Square — A cat silhouette that works year-round but feels especially right for Halloween season. Advanced.

A Halloween granny square blanket mixing skulls, webs, ghosts, and cats in black, orange, and purple would be a breathtaking seasonal project.

3. Christmas and Holiday Granny Squares

The holiday season is a wonderful time to pull out unusual patterns, especially if you’re gifting handmade items. These Christmas-themed squares give you all the festive motifs you could want.

Snowflake Granny Squares

Christmas Tree Granny Squares

A holiday blanket mixing snowflakes and Christmas trees — perhaps with a border in festive red — would make an heirloom gift.

Tiny Mushroom Granny Square

One of the most charming entries in the unusual collection is the Tiny Mushroom Granny Square. In a creative twist, the first round of a basic granny square is shaped to form a tiny mushroom cap at the center. It’s actually quite beginner-friendly and works wonderfully in earthy, cottagecore-inspired palettes — terracotta, sage, cream, and brown.

4. Unusual Flower and Floral Granny Squares

The classic granny square already has flower-like symmetry at its core. But these unusual floral designs push that concept much further, incorporating real flower species, layered petals, and botanical detail that goes well beyond a simple five-petal flower center.

Unique Flower-Centered Granny Squares

These squares feature specific flower species as their central motif, each with distinct petal shapes and color possibilities:

Unusual Floral Granny Squares

These squares use floral elements in more creative, less literal ways — combining flowers with hearts, geometric forms, or layered arrangements:

For wearable projects, flower granny squares truly shine when used in granny square tank tops, cardigans, and even skirts. A floral granny square top in a summer palette is one of the most-wanted crochet makes of recent years.

5. Unusual Circle Center Granny Squares

Traditional granny squares start with a round center that quickly transitions to the square shape. But these unusual circle-centered designs let the circular form do more of the visual work, incorporating lace-like openings, raised stitch techniques, and unexpected geometric framing.

These patterns are particularly beautiful when worked in two contrasting colors, letting the circle shape read clearly against the square frame.

6. Colored Granny Squares

Sometimes the most unusual thing you can do with a classic granny square is rethink the color. These patterns take the basic or solid granny square construction and use strategic color placement to create visually arresting results — no complex motif required.

These colored variations are excellent for using up scrap yarn and can be mixed and matched with other squares in a blanket. Color-blocked and diagonal designs are particularly popular for modern, minimalist crochet aesthetics.

7. Textured Granny Squares

Texture is arguably the most underexplored dimension of unusual granny square design. By incorporating stitches like BPDC (back post double crochet), FPDC (front post double crochet), bobble stitches, and gradient color changes, you can turn a flat, uniform square into something with genuine tactile and visual depth.

  • Archery Target Granny Square — Concentric textured rings give this the appearance of a bullseye target. Great in earthy or bold color combinations. Moderate.
  • Textured Sunburst Granny Square — A sunburst design where the rays have raised texture, giving the square real dimensionality. Moderate.
  • Gradient Textured Granny Square — A gradient color progression combined with textured stitches. The result is a square that looks like it was carved as much as crocheted. Moderate.
  • Textured Solid Granny Square — A solid square with post stitches creating a raised, basket-weave-adjacent texture. Moderate.
  • Texture Basic Granny Square — The classic basic granny square construction with post stitches added to give the clusters three-dimensional texture. Moderate.

Textured granny squares are especially satisfying to work with because the transformation from round to round is very visible — and the finished fabric has a quality to it that photography doesn’t fully capture. These squares really need to be held in the hand to be appreciated.

How to Use Unusual Granny Squares in Projects

One of the most common questions about unusual granny square patterns is: can these really be used in the same projects as traditional granny squares? The answer is almost always yes — with a little planning.

Blankets and Throws: Mix unusual squares with solid background squares to let the motifs breathe. A skull square surrounded by four solid black squares is far more dramatic than a blanket of all skull squares.

Granny Square Cardigans and Sweaters: Flower and floral squares have become enormously popular in wearables. Keep motif squares at the front or back panels and use simpler squares at the sides and sleeves.

Bags and Totes: Geometric and poker suit squares work brilliantly for bags, where their graphic quality can really shine.

Wall Hangings: Halloween skull squares, moon and sun squares, and snowflake squares all make stunning wall hangings, mounted on dowels and displayed seasonally.

Cushion Covers: A single large unusual motif square, or a 2×2 arrangement of four coordinating squares, makes a gorgeous cushion cover.

Tips for Working with Unusual Granny Square Patterns

  1. Swatch first. With unusual patterns, gauge matters more than it does with simple squares. If your motif is slightly too large or small, the whole visual impact changes.
  2. Read through the full pattern before starting. Many unusual granny squares involve techniques (like appliqué, surface slip stitches, or color changes mid-row) that are much easier to understand when you have the full picture.
  3. Use stitch markers liberally. When working motifs with lots of shaping, stitch markers at key reference points prevent counting errors that can be hard to diagnose later.
  4. Block everything. Figural and flower motifs especially benefit from blocking, which opens up the lace sections and helps the motif lie flat inside its square frame.
  5. Keep a yarn journal. When working large blankets with unusual squares in multiple colors, keep notes on which colorways you used for which squares. Reproducing a square six months later from memory is frustrating.
