There are two types of Halloween crafters: the ones who do elegant autumn decorating with neutral pumpkins and dried flowers… and the rest of us, who see a black crochet spider coaster and immediately think, “Yes, that absolutely needs to sit under my coffee mug.”
This free crochet spider coaster pattern is a quick, spooky, and slightly ridiculous little Halloween crochet project that is perfect for using up black yarn from your stash. It works beautifully as a Halloween mug rug, party table decoration, office desk coaster, or handmade trick-or-treat party favor.
And because it is mostly made from basic crochet stitches, this is a great seasonal project for confident beginners who want something more exciting than another plain circle coaster. The legs make it look impressive, but the actual construction is very manageable once you get into the rhythm.
If you enjoy quick seasonal crochet makes, you might also like browsing our Halloween crochet patterns on CraftGossip, especially if your craft table is already starting to look like a haunted yarn cupboard. For more small handmade gift ideas, our crochet coaster pattern roundups are also a lovely place to find stash-busting projects you can make in an evening.
A good black cotton yarn works nicely here because it gives the coaster a little structure and helps the spider sit flat. If you are making a full set, this is also a handy project for using leftover worsted weight yarn. A basic crochet hook set, tapestry needles, and small safety eyes or craft eyes are easy to find on Amazon, and Mary Maxim is always worth checking if you are stocking up on yarn for Halloween, fall, and Christmas crochet projects.

Round 7: Ch 1, sc in each st around. Join. — 48 sts
Do not fasten off if you want to work the head directly from the body.
Spider Head
The head is worked onto one side of the body.
Lay the circle flat and choose one section to become the front of the spider.
Row 1: Ch 1, sc in next 10 sts across the edge of the body. Turn.
Row 2: Ch 1, sc2tog, sc in next 6 sts, sc2tog. Turn. — 8 sts
Row 3: Ch 1, sc in each st across. Turn. — 8 sts
Row 4: Ch 1, sc2tog, sc in next 4 sts, sc2tog. — 6 sts
Fasten off and weave in the end.
This creates a small rounded head shape at the front of the coaster.
Spider Legs
You will make 8 legs, 4 on each side of the body.
Join yarn to the side of the spider body near the head.
Leg 1
Ch 13.
Sl st in 2nd ch from hook and in each ch back to the body.
Sl st into the next body stitch to secure.
Leg 2
Ch 15.
Sl st in 2nd ch from hook and in each ch back to the body.
Sl st into the next body stitch to secure.
Leg 3
Ch 15.
Sl st in 2nd ch from hook and in each ch back to the body.
Sl st into the next body stitch to secure.
Leg 4
Ch 13.
Sl st in 2nd ch from hook and in each ch back to the body.
Fasten off.
Repeat on the opposite side of the body, spacing the legs as evenly as possible.
Don’t worry if the legs are not perfectly identical. Real spiders are not exactly winning beauty pageants either, and a little unevenness actually makes these look more fun and handmade.
Eyes
You can finish the spider in one of three ways:
Use small plastic craft eyes and attach them with a glue gun.
Stitch two small white French knots using embroidery thread.
Crochet two tiny white circles and sew them to the head.
For a child-safe version, embroidered eyes are the best option.
Finishing
Weave in all loose ends.
Lay the spider flat and gently shape the legs with your fingers. If your spider wants to curl up like it has stage fright, lightly block it by pinning it flat on a blocking mat and misting with water. Let it dry fully before using.
For extra stiffness, you can lightly spray the coaster with fabric stiffener or starch, especially if you want to use it as Halloween party decor.
Helpful Tips For Making Crochet Spider Coasters
If your coaster is curling, your tension may be too tight or your hook may be too small. Try going up half a hook size for a flatter finish.
Cotton yarn gives a firmer coaster, while acrylic yarn makes a softer, slightly fuzzier spider.
For a creepier Halloween look, use all black yarn and tiny white eyes. For a cute kid-friendly version, try purple, orange, charcoal, or even variegated Halloween yarn.
You can also make a whole set with different leg lengths and eye placements. They look especially fun scattered across a Halloween party table with mugs, candy bowls, pumpkins, and fake cobwebs.
Creative Variations
Make a spider garland by crocheting several spiders and attaching them to a long chain.
Turn one into a Halloween applique for a tote bag, trick-or-treat sack, or sweater.
Use chunky yarn and a larger hook to make an oversized spider placemat.
Add a tiny red stitched mark on the back for a black widow-inspired version.
Make a set of four and tie them with ribbon for a quick handmade Halloween hostess gift.
Why This Halloween Crochet Project Works
Small seasonal crochet projects are always popular because they are quick, affordable, and easy to gift. This crochet spider coaster has that perfect mix of useful and silly, which is exactly why Halloween crafts are so much fun.
It is also a brilliant stash-buster. You only need a small amount of yarn, and if you already have a hook, scissors, and a yarn needle, you can probably make one without buying anything new. Though, let’s be honest, “I needed black yarn for spiders” is a completely acceptable excuse to add three more skeins to the basket.
Use these crochet spider coasters under mugs, scatter them across your Halloween table, or make a batch for coworkers, teachers, or party guests. They are quick enough to make in multiples and spooky enough to make people smile.
