Spooky Skull Granny Square – Free Crochet Pattern

If you’ve ever wanted to add a little playful spookiness to your crochet projects, this Skull Granny Square is the perfect place to start. I like to think of it as a fun mash-up between the classic granny and a quirky Halloween motif. The square itself works up to about 2 inches, making it just right for mixing and matching with your regular grannies, or for creating statement pieces like coasters, bunting, or even an edgy blanket.

What I love about this design is that it’s approachable even if you’re not a granny square expert yet. The rounds are short, the stitches are familiar, and you get a neat little skull effect without too much fuss. You can keep it classic with white or grey yarn for a traditional “bone” look, or go bold with neon shades for a more playful vibe.

What you need

• Small amounts of 4-ply cotton yarn (I used black and white for contrast)
• 2.3 mm crochet hook
• Stitch marker
• Scissors

Instructions

Skill Level

Confident beginner to intermediate.

You will need to know how to work basic crochet stitches and how to crochet evenly around a shaped motif.

Crochet Terms

This pattern uses US crochet terms.

Finished Size

Finished size will vary depending on your yarn, hook size, and tension.

As a guide:

• DK yarn will make a square approximately 4–5 inches across.
• Worsted weight yarn will make a square approximately 5–6 inches across.

If you want a much smaller square, you can use 4-ply cotton and a smaller hook, but the larger mockup-style square is better suited to DK or worsted weight yarn.

What You Need

• DK or worsted weight yarn in two colours
• Colour A: white, cream, grey, or bone colour for the skull
• Colour B: black or another dark colour for the background
• Small amount of black yarn for the eyes and nose
• Crochet hook suitable for your yarn
• Yarn needle
• Scissors
• 4 stitch markers

A smooth cotton or acrylic yarn works well for this project. If you are making several squares for a blanket or garland, use the same yarn weight throughout so your squares finish at a similar size.

Abbreviations

• ch — chain
• dc — double crochet
• hdc — half double crochet
• sc — single crochet
• sl st — slip stitch
• st/sts — stitch/stitches
• sp — space
• MR — magic ring
• rep — repeat

Notes Before You Begin

The skull is worked first in Colour A.

The square border is then worked around the skull in Colour B.

The ch-3 spaces in the border rounds form the corners of the square.

The first border round is a shaping round, so do not worry if it looks a little uneven at first. The goal is to place the skull in the centre and create four clear corners.

Before starting the border, lay the skull flat and imagine a square around it. Use stitch markers to mark the four corner positions: lower right, upper right, upper left, and lower left.

If your square cups, add one or two extra stitches along the sides. If it ripples, remove one or two stitches along the sides.

Skull Centre

Using Colour A, make a magic ring.

Round 1

Ch 2. This does not count as a stitch.

Work 9 dc into the magic ring.

Ch 5.

Work 1 dc into the magic ring.

Ch 3.

Work 1 dc into the magic ring.

Ch 5.

Pull the magic ring closed.

Join with a sl st to the top of the first dc.

You should now have:

• 11 dc stitches
• two ch-5 spaces
• one ch-3 space

The two ch-5 spaces help form the sides of the skull, and the ch-3 space helps shape the lower part of the face.

Round 2

Ch 1.

Sc in each of the first 9 dc.

Work 6 sc into the first ch-5 space.

Work 1 sc into the next dc.

In the ch-3 space, work:

Sl st, ch 2, 2 dc, ch 2, sl st.

Work 1 sc into the next dc.

Work 6 sc into the second ch-5 space.

Join with a sl st to the first sc.

Fasten off Colour A and weave in the ends.

This completes the basic skull shape.

Skull Face Details

Using a small amount of black yarn and a yarn needle, stitch two small round eyes onto the skull.

Place the eyes evenly on either side of the centre, about halfway down the skull.

For the nose, stitch a small upside-down triangle between the eyes and slightly lower.

Keep the facial features small. If the eyes are too large, the skull can start looking more like a surprised ghost, which is still cute, but not quite what we are going for here.

Marking the Corners

Lay the skull flat with the rounded head at the top and the jaw section at the bottom.

Using stitch markers, mark four points around the skull where the square corners will sit:

• Marker 1: lower right side of the skull
• Marker 2: upper right side of the skull
• Marker 3: upper left side of the skull
• Marker 4: lower left side of the skull

These markers do not need to be placed into exact stitch numbers. They are guides to help you create an even square around the skull.

Square Border

Join Colour B at Marker 1, near the lower right side of the skull.

Round 3

Ch 3. This counts as the first dc.

Work 1 dc in the same place.

Ch 3.

Work 2 dc in the same place.

This forms the first corner.

Working evenly along the first side of the skull toward Marker 2, work:

1 dc, 3 hdc, 1 dc.

At Marker 2, work:

2 dc, ch 3, 2 dc.

Working evenly along the top of the skull toward Marker 3, work:

1 dc, 3 hdc, 1 dc.

At Marker 3, work:

2 dc, ch 3, 2 dc.

Working evenly along the next side of the skull toward Marker 4, work:

1 dc, 3 hdc, 1 dc.

At Marker 4, work:

2 dc, ch 3, 2 dc.

Working evenly along the final side back to the beginning corner, work:

1 dc, 3 hdc, 1 dc.

Join with a sl st to the top of the beginning ch 3.

At the end of this round, you should have four ch-3 corner spaces.

Do not worry if the stitch placement is not identical on every side. The most important thing is that the skull sits in the centre and the four corners are evenly placed.

Round 4

Ch 3. This counts as the first dc.

Dc in each stitch across to the first ch-3 corner space.

In the corner space, work:

2 dc, ch 3, 2 dc.

Dc in each stitch across the next side.

In the next corner space, work:

2 dc, ch 3, 2 dc.

Repeat around the square, working dc stitches evenly along each side and 2 dc, ch 3, 2 dc in each corner space.

Join with a sl st to the top of the beginning ch 3.

Fasten off or continue if you would like a larger square.

Optional Extra Border Round

If you would like a larger square, continue with Colour B or join a new colour.

Ch 3. This counts as the first dc.

Dc in each stitch across the side.

In each ch-3 corner space, work:

2 dc, ch 3, 2 dc.

Repeat around the square.

Join with a sl st to the top of the beginning ch 3.

Fasten off and weave in ends.

Finishing

Weave in all ends securely.

Gently block the square so the sides sit straight and the skull sits neatly in the centre.

Pin the square into shape, making sure all four corners are square. Lightly steam or wet block depending on the yarn you have used.

Allow the square to dry completely before joining it to other squares or using it in a project.

Pattern Amendment Note

This pattern has been updated to make the finished square match the mockup more closely and to help clarify the corner placement.

Please note the following corrections and clarifications:

• Use DK or worsted weight yarn for a larger mockup-style square.
• The black eyes and small triangle nose are added after the skull centre is crocheted.
• Mark the four corner positions with stitch markers before beginning Round 3.
• Round 3 is worked evenly around the skull to form the first square border.
• Side stitch counts may be adjusted slightly if needed to keep the skull centred and the square flat.
• This pattern uses US crochet terms.

This amendment should help readers who were unsure where to place the first corner after completing the skull centre.

Project Ideas

Use one skull square as a Halloween coaster.

Join several squares together to make spooky crochet bunting.

Alternate skull squares with plain black, white, orange, purple, or grey granny squares for a Halloween blanket.

Sew one onto a tote bag for a fun seasonal detail.

Use a single square as the front panel for a small trick-or-treat bag.

Make a set in different skull colours for a quirky Halloween garland.

You could even make a whole pile of these in stash yarn and finally use up those odd little scraps we all insist on keeping because “they’ll come in handy one day.” This is their day.

Quick Tips

For a cleaner skull shape, keep your stitches snug but not tight.

Use a yarn needle to shape the eyes and nose neatly.

If the square looks uneven after Round 3, keep going. Round 4 and blocking will tidy it up.

For a more gothic look, try a cream skull on a black background.

For a brighter Halloween version, use orange, purple, lime green, or hot pink for the background.

Suggested Uses

This spooky skull granny square can be used for:

• Halloween blankets
• Crochet bunting
• Trick-or-treat bags
• Gothic crochet cushions
• Halloween coasters
• Crochet garlands
• Tote bag appliqués
• Seasonal cardigan patches
• Spooky table décor

Once you have made one, it is very easy to get carried away and make a whole stack. Which is exactly how “just one Halloween square” somehow becomes a blanket. We have all been there.
