If you fancy a crochet project you can start and finish in an evening, crochet coasters are hard to beat. They use a few metres of yarn, a couple of basic stitches, and at the end you've got something you'll actually use under your morning cuppa. That makes them one of the best first makes going, whether you've just picked up your first crochet kit or you're a cross stitcher branching out into yarn.
They're also a lovely summer make. A set in bright cotton comes together quickly, and a coordinating set of three or four looks properly thoughtful as a gift.
A quick heads-up before we start: this guide uses UK crochet terms, with the US name in brackets the first time each one comes up. A lot of free patterns and videos online are American, and the same words mean different stitches on each side of the Atlantic, so it's worth knowing which you're following. We'll walk through a round coaster and a square one, sort out which yarn to use, and deal with the thing that trips up almost every beginner: coasters that curl up instead of lying flat.
And if your first one comes out a bit wonky? That's completely normal. Everyone’s does. Let's get into it.
Why Coasters Are a Great First Crochet Project
Coasters tick every box for a beginner project. They're small, so you're not committing to weeks of work. They use hardly any yarn, so you can raid your stash or buy a single ball. And they use the most basic stitches, so there's nothing fiddly to master before you see a finished result.
That fast finish matters more than it sounds. Nothing builds confidence like actually completing something, and a coaster gives you that win in an hour or so rather than a month. If your tension wobbles or a stitch goes astray, it barely shows on a project this size, which takes the pressure off while you're still finding your rhythm.
There's a nice bonus too. The repetitive, rhythmic motion of crochet is calming, it gives your hands something to do away from a screen, and you finish with something to show for the time. So a quiet evening's stitching does you good and leaves you with a useful little make at the end.
Are crochet coasters actually a good idea in practice? Yes. Made in cotton, they're washable, they soak up the drips from a cold glass in summer, and they protect your table from hot mugs. A matching set also makes one of the easiest handmade gifts there is, which is why they turn up so often in our crochet gift ideas.

What You'll Need
One of the best things about coasters is how little you need to begin. Here's a short list of the useful tools and accessories we recommend.
Cotton yarn
Cotton is the one to reach for, and it's worth knowing why. It's absorbent, so it copes with condensation from a cold drink, it's machine washable, and it handles the heat of a mug far better than acrylic. A double knit (DK) or aran weight cotton is the easiest to work with as a beginner. Acrylic will do in a pinch, but it's less absorbent and can flatten over time, so cotton is the better choice for something that sits under a wet glass.
A crochet hook
Check the ball band for the recommended size and use that as your starting point. One useful tip: going down a size from the label gives you tighter, firmer stitches, which makes for a sturdier coaster that lies flatter.
Scissors
To cut your yarn and avoid fraying threads, a pair of quality embroidery scissors are a must-have.
A darning or tapestry needle
For weaving in the ends at the finish.
That really is it. If gathering supplies feels like faff, a crochet kit takes the guesswork out by giving you the right yarn, the right hook, and a tested pattern in one box. We don't have a coaster kit as such, but our crochet kits are a gentle way into the craft if you'd rather not piece everything together yourself.

Which Crochet Stitch Is Best for a Coaster?
For most coasters, UK double crochet (US single crochet) is your friend. It creates a dense, firm fabric that sits flat and gives your table proper protection from heat and moisture. It's also one of the first stitches most people learn, so it's a comfortable place to start.
If you want something a little lacier and quicker to work up, UK treble crochet (US double crochet) makes a taller, more open stitch. It's lovely for a summery, airy look, though it gives a bit less coverage. For your first coaster, stick with double crochet and you won't go far wrong.
How to Crochet a Round Coaster (Step by Step)
A round coaster is worked in the round, building outwards from the centre. Here's how to make one in UK double crochet (US single crochet).
- Start with a magic ring. This is a loop of yarn you can pull tight once you've worked into it, which closes up the hole in the middle neatly. If you find the magic ring fiddly, chain four and join with a slip stitch into the first chain to make a small ring instead. Both work fine.
- Round 1: Work six UK double crochet into the ring, then pull the tail to close the centre. You'll have a snug little circle of six stitches.
- Round 2: Slip stitch into the first stitch to join the round together then chain 1 and start round 2. This needs to be done at the end of each round. You can use a stitch marker to track where the start of each round is.
- Round 3: Work one double crochet in the first stitch, then two in the next, and repeat that all the way round. You'll add six stitches, giving you eighteen.
- Round 4 onwards: Keep adding six stitches per round, putting one extra plain stitch between the increases each time (so round four goes "two double crochet, then one in each of the next two", and so on). This steady increase is what keeps the circle flat, which we'll come back to.
- Keep the increases moving. Don't stack your increases directly on top of each other from round to round. Stagger them so they land in different places, and your coaster stays round rather than turning into a hexagon with pointy corners.
- Finish when it's the size you want. Around 9 to 11cm across (roughly 3.5 to 4 inches) is a comfortable coaster that fits under most mugs and glasses. Fasten off, leaving a tail, and weave the end in with your needle.
If your circle starts cupping or curling as you go, don't panic. That's the most common beginner hiccup, and the next section but one covers exactly how to fix it.
How to Crochet a Square Coaster
If working in the round feels daunting, a square coaster worked flat in rows is a gentler place to start. There's no circle to keep flat, just straightforward back-and-forth rows.
- Make a foundation chain. Chain around 15 to 18 stitches for a coaster-sized square. The exact number sets your width, so you can adjust it up or down.
- Row 1: Work one UK double crochet (US single crochet) into the second chain from your hook, then one into each chain along the row.
- Turn and repeat. Chain one to turn, then work a double crochet into each stitch back along the row. Keep your stitch count the same on every row so the edges stay straight.
- Carry on until your square is as tall as it is wide. Hold it up now and then to check it's roughly square.
- Neaten the edges (optional). A simple round of double crochet worked all the way around the outside tidies up the sides and gives a nice finish. Work a few extra stitches into each corner so it turns the corner without pulling in.
- Fasten off and weave in your ends.
To make a bigger or smaller square, just add or remove chains at the start. More chains means a wider coaster.
How to Stop Your Coaster Curling
Here's the problem almost every beginner hits: your coaster starts curving up at the edges like a little bowl instead of sitting flat. It's frustrating, but it's fixable, and once you know the causes it stops happening. Most guides explain this for flat rows and go quiet when it comes to circles, so let's cover both.
Your tension is too tight
Pulling your stitches tight is the usual culprit. Tight stitches have no room to relax, so the fabric draws in and curls. Try loosening your grip and letting the yarn flow a little more freely. If your hands naturally work tight no matter what you do, the fix below solves it too.
Your hook is too small for the yarn
A hook that's too small forces tight, stiff stitches. Going up a hook size gives each stitch more space to sit flat. If a coaster keeps curling with the recommended hook, size up and see the difference.
You're not increasing enough (this is the circle one)
A flat circle needs a set number of new stitches added every round, six when you're working in double crochet. Add too few and the circle can't lie flat, so it cups upward into a bowl. If your round coaster is curling, count your increases and make sure you're adding six per round as set out above. Too many increases and it'll ripple and wave at the edges instead, so it's a balance.
Block it at the end
Blocking sounds technical, but for a coaster it's simple. Lay the finished coaster flat, give it a light spray or steam with an iron held just above it (don't press down), gently ease it into shape, and pin it down until it dries. Cotton takes to this beautifully. A quick block will rescue a first attempt that came out slightly wonky and leave it sitting properly flat.
Easy Ways to Vary Your Coasters
Once you've got the basic method, there's plenty of room to play without learning anything new.
Colour is the easiest place to start. A set of three or four coasters in coordinating shades looks pulled-together and makes a lovely gift, and a bright summery palette suits the season. You can work simple stripes by changing colour at the start of a round or row, which is a gentle way to practise joining a new yarn.
Once you're comfortable, textured stitches like the spike stitch or a granny-square style open up more designs, though there's no rush to get there. If you fancy trying a granny square next, our granny square guide walks you through it. And for a bigger beginner make in the same summery spirit, our guide to how to crochet a tote bag is a natural next step.
The nice thing is that every variation is still a quick, low-pressure make. You can try a new colourway or stitch on a single coaster in an evening, with barely any yarn at stake if it doesn't work out.
Frequently Asked Questions
What is the best yarn for crochet coasters?
Cotton, without a doubt. It's absorbent, so it copes with condensation from a cold drink, it's machine washable for when it inevitably catches a spill, and it stands up to the heat of a mug far better than acrylic. A DK or aran weight cotton is easiest for beginners to handle.
What is the best stitch for a crochet coaster?
UK double crochet (US single crochet) is the go-to. It makes a dense, firm fabric that lies flat and protects your table. UK treble crochet gives a taller, lacier finish if you want something more open, but double crochet is the safest choice for a sturdy everyday coaster.
How big should a crochet coaster be?
Around 9 to 11cm across, or roughly 3.5 to 4 inches, suits most mugs and glasses. It's easy to adjust, though. For a round coaster, simply work more or fewer rounds. For a square one, add or remove chains at the start.
Why does my crochet coaster curl up?
Usually tight tension, a hook that's too small, or too few increases when working in the round. Loosen your stitches, try going up a hook size, and make sure a round coaster gains six stitches per round. A quick block at the end will flatten out anything that's still slightly cupped.
Can beginners crochet coasters?
Absolutely, and they're one of the best first projects there is. They use basic stitches, take about an hour, and use very little yarn, so there's low pressure if your first attempt is a little uneven. It gets easier fast.
Do I need to block a crochet coaster?
You don't have to, but it helps. Blocking means wetting or steaming the finished coaster, easing it into shape, and pinning it flat to dry. It's a quick step that makes a wobbly first coaster sit properly flat, and cotton responds to it well.
Ready to Start Stitching?
That's everything you need to make a simple crochet coaster, round or square, and keep it lying flat. It's a quick, useful summer make, and once you've made one you'll probably find yourself running up a whole set.
