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

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

Instructions

There is something particularly satisfying about adding a spooky surprise to a traditional crochet square. From a distance, it looks like a bold granny-style motif. Look a little closer and there is a cheeky skull staring back at you.

The skull is worked first and then surrounded with a contrasting border. Four stitch markers help position the corners so the skull sits neatly in the centre of the finished square.

This shaping makes the project best suited to confident beginners or intermediate crocheters. You will need to know how to chain, slip stitch, single crochet, half double crochet and double crochet.

If you would like to practise the traditional square construction first, try our basic crochet granny square pattern. Once you are comfortable identifying corner spaces, this spooky variation will be much easier to manage.

Crochet Terms

This pattern uses US crochet terminology.

Skill Level

Confident beginner to intermediate.

Finished Size

The finished size will depend on your yarn, hook and crochet tension.

As a general guide:

DK yarn with a 4 mm hook will produce a square approximately 10 to 13 cm across.

Worsted-weight yarn with a 5 mm hook will produce a square approximately 13 to 15 cm across.

The dimensions are approximate. Crochet one square and block it before beginning a blanket or another project requiring several matching squares.

Abbreviations

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

Pattern Notes

The beginning ch-3 counts as the first dc unless otherwise stated.

The beginning ch-1 does not count as a stitch.

Instructions inside parentheses are worked into the same stitch or space.

The skull is worked first in Colour A.

The square border is worked in Colour B.

Four ch-3 spaces form the corners of the square.

Round 3 is worked evenly around a shaped motif rather than into a traditional circular round. Place the four corner markers before joining the background yarn.

Each side of Round 3 contains five stitches between the corner groups.

Maintain the same yarn, hook and border placement when making multiple squares.

Skull Centre

Using Colour A, make an MR.

Round 1

Ch 2. This beginning chain does not count as a stitch.

Work 9 dc into the MR.

Ch 5 and work 1 dc into the MR.

Ch 3 and work 1 dc into the MR.

Ch 5.

Pull the MR closed.

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

Round count: 11 dc, two ch-5 spaces and one ch-3 space.

The group of 9 dc forms the rounded top of the skull. The two ch-5 spaces and central ch-3 space help form the lower face and jaw.

Round 2

Ch 1. This does not count as a stitch.

Sc in each of the first 9 dc.

Work 6 sc in the first ch-5 sp.

Sc in the next dc.

In the ch-3 sp, work:

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

Sc in the next dc.

Work 6 sc in the second ch-5 sp.

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

Thread a yarn needle with a length of black yarn.

Embroider two small round or oval eyes on the upper half of the skull. Position the eyes evenly on either side of the centre.

Embroider a small upside-down triangle below and between the eyes to create the nose.

Secure the yarn ends neatly on the back of the skull.

Keep the facial features fairly small. Large eyes can make the skull look more like a surprised ghost, which is still rather cute, but not quite the look we are aiming for.

Positioning the Corners

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

Place four removable stitch markers evenly around the outer edge of the skull:

Marker 1: lower-right edge
Marker 2: upper-right edge
Marker 3: upper-left edge
Marker 4: lower-left edge

The markers should sit approximately equal distances apart. They identify where the four corner groups will be anchored.

Make sure there is enough space between each pair of markers to work five evenly distributed side stitches.

If necessary, move the markers slightly until the four sections appear balanced. Taking an extra minute here is much easier than pulling the border apart later. Ask me how I know.

Square Border

Join Colour B at Marker 1 on the lower-right edge of the skull.

Remove each stitch marker as you reach it.

Round 3

At Marker 1, work:

(Ch 3, 1 dc, ch 3, 2 dc).

The beginning ch-3 counts as the first dc. You now have four dc and one ch-3 corner sp at Marker 1.

Working evenly along the edge of the skull towards Marker 2, work:

1 dc, 3 hdc and 1 dc.

At Marker 2, work:

(2 dc, ch 3, 2 dc).

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

1 dc, 3 hdc and 1 dc.

At Marker 3, work:

(2 dc, ch 3, 2 dc).

Working evenly along the next edge towards Marker 4, work:

1 dc, 3 hdc and 1 dc.

At Marker 4, work:

(2 dc, ch 3, 2 dc).

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

1 dc, 3 hdc and 1 dc.

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

Round count: 36 sts and four ch-3 corner spaces.

Check that the skull is centred and the four corners are reasonably even before continuing.

Round 4

Sl st in the next dc and then sl st into the first ch-3 corner sp.

In the same corner sp, work:

(Ch 3, 1 dc, ch 3, 2 dc).

Dc in each of the next 9 sts.

Repeat the following sequence three times:

Work (2 dc, ch 3, 2 dc) in the next ch-3 corner sp. Dc in each of the next 9 sts.

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

Round count: 52 dc and four ch-3 corner spaces.

Fasten off if you are happy with the size, or continue with the optional additional border.

Optional Additional Border

Sl st in the next dc and then sl st into the first ch-3 corner sp.

In the same corner sp, work:

(Ch 3, 1 dc, ch 3, 2 dc).

Dc in each of the next 13 sts.

Repeat the following sequence three times:

Work (2 dc, ch 3, 2 dc) in the next ch-3 corner sp. Dc in each of the next 13 sts.

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

Round count: 68 dc and four ch-3 corner spaces.

Fasten off and weave in all remaining ends.

Finishing

Lay the completed skull granny square on a blocking mat.

Gently shape the sides and pin out all four corners. Make sure the skull sits upright and approximately in the centre.

Wet block or lightly steam the square using a method suitable for your yarn. Never place a hot iron directly onto acrylic yarn.

Allow the square to dry completely before removing the pins.

Troubleshooting the Border

If the skull pulls towards one corner, undo Round 3 and reposition the stitch markers more evenly.

If the square cups, check that all five side stitches were distributed across the edge rather than crowded into one attachment point.

If the border ripples, the stitches may have been worked too loosely or placed too close together.

If you are making several squares, compare each new square with your first blocked square before fastening off.

Ways to Use Your Skull Granny Square

Use one square as a Halloween coaster or decorative patch.

Join several squares to make spooky crochet bunting.

Alternate skull squares with plain black, orange, green or purple squares to make a Halloween blanket.

Turn four or nine squares into a gothic crochet cushion cover.

Add one to the front of a handmade trick-or-treat bag.

Use a single square as a statement pocket on a cardigan or tote bag.

For a smaller Halloween accessory, try our crochet skull pin pattern. You could also add a wonderfully creepy table decoration with this Halloween eyeball dishcloth crochet pattern.

Once you have made one skull square, it is very easy to get carried away and make a whole stack. This is also an excellent excuse for keeping all those small leftover balls of yarn because, for once, they really have come in handy.
