Crochet Spiderweb Granny Square Pattern for Halloween

Introduction

The Crochet Spiderweb Granny Square is the perfect project to capture the playful spirit of Halloween. This eye-catching square features a crisp white spiderweb at its center, surrounded by a classic granny square border in deep green, making it both festive and striking. An adorable black or dark green spider applique completes the design, adding a whimsical touch. Whether used on its own as a coaster, joined with others for a fun Halloween throw, or incorporated into garlands and wall hangings, this granny square is sure to be a conversation starter. The open lacework of the web makes the texture light, while the dense border provides structure, making it an interesting and versatile motif. This pattern is enjoyable to make and even more delightful to display, bringing playful Halloween vibes to your handmade decor.

This project is an excellent way to use up small amounts of yarn and practice several crochet techniques, including making magic rings, working in the round, making granny square corners, and crafting tiny three-dimensional appliques. The balance of structure and lacy openness makes the spiderweb granny square perfect for adventurous beginners and seasoned crocheters alike who want a quick, satisfying seasonal make.

Project Overview

The spiderweb granny square is constructed in several stages. First, the web itself is crocheted in rounds with white yarn, beginning at the center. Then, the green border is added using traditional granny square techniques to create the frame. Finally, a small spider applique is made separately and sewn onto the square as a decorative embellishment. The various elements—center, border, and applique—are joined seamlessly to create a cohesive and festive motif.

The web is worked in joined rounds for a symmetrical look.
The border transforms the circular web into a neat square.
The spider is made in pieces and stitched on last.

Skill Level

Advanced Beginner. This pattern is accessible for those comfortable with basic stitches and ready to try a few new skills. You should be able to work in the round, change colors, and make small pieces for appliques. Detailed step-by-step instructions make it approachable for those new to granny squares and applique work.

Materials

Yarn: DK (Light Worsted, Category 3) cotton or acrylic yarn. Approximate recommendations:

White: 10 g (for web center)
Green: 15 g (for border and spider)
Optional: Black (for spider applique if you prefer a black spider) about 2 g

Crochet Hook: 4.0 mm (G-6) or size to obtain gauge
Tapestry Needle: Large eye for sewing in ends and attaching applique
Scissors
Stitch Markers: Useful for marking the beginning of rounds or chain spaces
Optional: Blocking mats and pins for shaping

Finished Size

Each completed spiderweb granny square measures approximately 10 cm by 10 cm (4 inches by 4 inches) after light blocking. The spider applique adds a slight three-dimensional element but does not significantly alter the overall dimensions. To adjust the size, use a lighter or heavier yarn and adapt hook size accordingly, keeping in mind that this will change both the finished square and the size of the spider motif.

Gauge

Approximate gauge (before blocking): 20 dc x 10 rows = 4 inches x 4 inches (10 x 10 cm) in granny square border pattern. For this motif, an exact match is not crucial, but a significant change in gauge will affect the finished square’s size and the proportions of the spiderweb. Make sure your web and border lay flat, not curling or ruffling.

Pattern Notes

Chains at the beginning of each round count as stitches unless stated otherwise.
All rounds except the applique are worked with the right side facing.
Rounds are joined with a slip stitch to the top of the starting chain.
Always change colors in the last pull-through of the final stitch of the round for a neat transition.
You may wish to mark the corners of the square border with stitch markers.
The web is worked in joined rounds, not continuous spirals, for symmetry.
Keep your tension even—especially on long chain segments in the web.
The spider is worked in two pieces: a flat body circle and separate legs, both sewn to the square.

Crochet Pattern Instructions

Center Web

With white yarn, begin with a MR. Ch 3 (counts as first dc), make 11 dc into MR. Tighten ring and sl st to top of beg ch-3 to join. (12 sts)
Round 2: Ch 1, *(sc in next dc, ch 4)* repeat from * to * around (total 12 sc and 12 ch-4 sp). Sl st to first sc to join. (12 sc, 12 ch-4 sp)
Round 3: Sl st into next ch-4 sp, ch 1, sc in same sp, ch 6. *(sc in next ch-4 sp, ch 6)* repeat around. Sl st to first sc to join. (12 sc, 12 ch-6 sp)
Round 4: Sl st into next ch-6 sp, ch 1, sc in same sp, ch 7. *(sc in next ch-6 sp, ch 7)* repeat around. Sl st to first sc to join. Fasten off white. (12 sc, 12 ch-7 sp)

Creating the Square Border

Join green yarn in any ch-7 sp. Ch 3 (counts as dc), (2 dc, ch 2, 3 dc) all in same sp (forms first corner). Ch 2, (3 dc in next ch-7 sp, ch 2) twice. *(3 dc, ch 2, 3 dc) in next ch-7 sp (corner); ch 2, (3 dc in next ch-7 sp, ch 2) twice* repeat from * to * around. Join with sl st to top of beg ch-3. (4 corners, each with 3 dc, ch 2, 3 dc; sides each with two 3-dc clusters and ch-2 sps)
Round 2 (Border): Sl st in next two dc and into ch-2 corner sp. Ch 3 (counts as dc), (2 dc, ch 2, 3 dc) in same corner sp. *Ch 1, 3 dc in next ch-2 sp, ch 1, 3 dc in next ch-2 sp, ch 1,* (3 dc, ch 2, 3 dc) in next corner sp; repeat from * to * around. Join with sl st to beg ch-3. Fasten off and weave in ends. (4 corners, each with 3 dc, ch 2, 3 dc, and sides with three 3-dc clusters)

Your square base is now complete. Proceed to spider applique.

Spider Applique

The spider can be created in black or green as shown. Work a flat body and sew on eight legs.

Body: With desired color, make a MR, ch 1. Work 6 sc into MR. Pull tight and join with sl st. Fasten off, leaving a long tail for sewing. (6 sc)
Legs (x8): Ch 8, sl st in 2nd ch from hook and each remaining ch (7 sl st back). Fasten off, leaving a tail to sew. Repeat for all 8 legs.

Alternatively, you can embroider the legs directly onto the square for a flatter look.

Assembly

Position body on the web, usually overlapping one side, to make it look like the spider is climbing.
With a tapestry needle and the long tail, stitch the spider’s body securely to the web. Weave in end beneath the applique.
Arrange and sew four legs to each side of the body, spacing them evenly. Stitch securely so they don’t pull loose.
Weave in all tails on the wrong side of the square.

Optional: Embroider two small eyes with a white or metallic yarn for extra character.

Assembly and Finishing

Once all elements are complete, double-check each color change and border row for any loose loops or uneven stitches. Use a tapestry needle to weave in all yarn tails on the wrong side of your square, making sure to anchor them well so the ends do not pop out later. If your spider legs are sticking out at odd angles, reshape gently with your fingers before sewing them down. Arrange the spider so it looks natural on the web—angled or climbing—then sew firmly into place.

To ensure your granny square lies flat and maintains a crisp shape, block lightly using steam or pin and mist-blocking. Lay the square on a blocking mat, stretch gently to square up corners, and pin in place. Once dry, remove pins. This step is especially important if you plan to join multiple squares into larger projects like afghans or bunting.

Customization Ideas

Try the web in orange or purple for extra Halloween drama, or make a set in assorted spooky shades.
Use sparkle or metallic yarn for the spider or its eyes for a whimsical effect.
Make several squares and join for a striking Halloween blanket, pillow cover, or table runner.
Attach a loop to one corner to turn the motif into a festive hanging ornament, or string along a chain for a garland.
Skip the spider applique for a simpler web motif, or add more spiders for extra fun.
Change up the yarn weight—fingering for mini coasters or chunky for oversized decor.

Troubleshooting

Curling Web: If your web pulls inward, check that your chains are not too tight. Work the ch-7 spaces loosely and use blocking to help shape.
Wavy Edges: Too many stitches or loose tension can make the border ruffle. Recheck your stitch count and use a slightly smaller hook if needed.
Square Too Small/Large: Swapping yarn weight or hook size will affect finished size. Adjust number of rounds or border rows as needed.
Uneven Color Changes: Change colors in the last loop of the previous stitch for a smoother transition.
Spider Won’t Lay Flat: Make sure the body is sewn down firmly, and arrange legs before attaching for symmetry.
Loose Tension: Use a consistent tension, especially on chain sections, and avoid overstretching joined seams.

Care Instructions

For best results, gently hand wash in cool water with mild detergent. Do not wring. Reshape and lay flat to dry, blocking again if necessary to maintain the square’s crisp shape. If using acrylic, a cool iron with a pressing cloth can help smooth edges. Always follow yarn manufacturer’s instructions for optimal durability when using for daily decor, such as coasters or garlands.

Final Notes

The Crochet Spiderweb Granny Square is as fun to make as it is to display! Remember to frequently count stitches as you go, especially in rounds with many chain spaces or increases. Adjust your tension as needed for uniform, crisp motifs. Let the finished photos inspire your arrangement and finishing touches. Have fun making your own haunted web—and enjoy a handmade Halloween!
