Sunday at the Pool Free Crochet Coaster Pattern

free crochet coaster pattern

Looking for quick last-minute gift ideas to make with leftover yarn from your stash? This free crochet coaster pattern is exactly what you need.

Christmas is around the corner and you probably need some fast gift ideas. At least I did. We have a friend’s Christmas dinner next week and the host asked us to each bring 2 small gifts for a game with a max budget of 5 dollars each. Not so easy to find around here so of course, my first reflex was to think what can I make. Designing something without knowing who it will be for is not easy. Crochet coasters are perfect for this: decorative, useful and convenient. I hope whoever receives these crochet coasters will love them!

This project is perfect for beginners, you only need to know the basic crochet stitches and it is short so you can enjoy the results fast and won’t get frustrated frogging hours of work if you make a mistake.

No time right now? Pin this free crochet coaster pattern for later!

Before you Start your Free Crochet Coaster Pattern


I used the following materials for this pattern:

  • 3 mm hook. I use this basic set. Each size has his own color which is very convenient and makes it easy to find the right hook straight away.
  • Cotton yarn: For 6 coasters I used about half a 50g skeins of  Schachenmayr Catania Originals per crochet coaster. Lovecrafts offers this yarn in 82 colors, you’ll definitely find some you love for your crochet coasters. This project is perfect to use up small leftovers of yarn!
  • T-pins for blocking. I like to use these.
  • Tapestry needle to weave in the ends. I love this set as it has different eye sizes for different yarn thickness and it comes in a small tube which is very convenient so I don’t lose them.

Finished Crochet Coaster Size

The finished size of these round crochet coasters is 10 cm / 4″ in diameter.


I use UK notations for this pattern.

  • st = stitch
  • ch = chain
  • dc = double crochet
  • htr= half double crochet
  • tr = treble crochet
  • ss = slip stitch

Sick of US vs UK conversion, metric vs imperial etc. Grab my free printable cheatsheets here!


  • Repeat the stitches mentioned between * * until the end of the round.
  • Each row starts with a ch1, ch2 or ch3 which counts as a dc, htr and tr respectively unless otherwise specified.

Tips and Tricks for the Free Crochet Coaster Pattern

If you have read my Mandala Placemat pattern, you’ll recognize most of these tips and tricks as the concept for this free crochet coaster pattern is the same.


Depending on how loose or how tight you crochet the sides might flare up a little. Don’t worry, there is absolutely no need to rip out all your hard work. This will be fixed by blocking your work.

What colors to choose for the free crochet coaster pattern

I used 3 different colors for these crochet coasters. I haven’t followed the same order for each coaster but have kept the proportions of each color equal. This makes each coaster unique while keeping a uniformity in the set. It is just what I did, you can make them however you want, using 1, 2, 5, 10 different colors and arranging them how you like. 10 might be hard as there are only 7 rounds in this pattern… You can even make each coaster a solid color but use a different one for each in the set. Possibilities are endless, don’t hesitate to let your creativity loose!

Weaving in the ends

Because each row uses a different color, a lot of ends need to be woven in. If you’re like me, weaving in ends is not your favorite part of a crochet project. Here are my tricks to make this process less tedious.

  • As the crochet coaster pattern is not too lacy, you can usually get away with crocheting the next round over the tail of the previous round.
  • After you have crocheted a few stitches over the tail of the previous round, leave about 3-4 cm of the tail and finish your round.
  • Weave in the end of the tail in the opposite direction. With this method, you only have to do half of the weaving in process per tail.
  • When you start a new round, don’t start where you finished the previous one. Start somewhere different at random. Having all your ends in the same section of the coaster will make an extra layer, which you want to avoid. You don’t want to see where you started your rows in your finished coaster, this trick makes them nearly invisible.
  • When I start a row, I tag along the tail and crochet with a double yarn for a couple of stitches. It’s not perfect but I find as these are at random around your coaster, they are not too visible and it makes you save a lot of weaving in ends time. If you don’t like it, you can leave your tail and weave it in afterwards like you would normally do.

The Actual Free Crochet Coaster Pattern

For the visual learners, chart version is available at the bottom.

Round 1: Make 8 puff stitches in a magic ring. Don’t forget to lock each one with a ch1. Finish the round with a ss in the 1st puff. But don’t pull to close the ring yet!

Round 2: Join yarn in between 2 puff stitches, ch3, tr1 in the same space, ch2. *2tr in each puff, ch2 *. Finish round with a ss in the 3rd ch of the ch3. Now you can finally pull the magic ring closed as tight as possible.

That’s it for the crocheting part of the free crochet coaster pattern.

You’re almost done, you only have some finishing touches left!

If you are not familiar with crochet charts, my Conquer Charts & Graphs workshop is there to help you!


I usually don’t like the finishing touches of a project. Once I have crocheted the last stitch, I wish I could start enjoying my project straight away. Unfortunately, the last few steps make a huge difference. So, let’s get it over quickly.

Don’t skip this step as it can make a huge difference. Read my detailed tutorial on why block, how-to, and all my tips and tricks if you need help.

The first step is to waive in all the ends and cut off any remaining threads.

Then you need to block your crochet coaster. This step will remove any flaring up or uneven tension in your work and make it look it’s absolute best. It took me years to discover blocking. I used to be disappointed at the end of each project because of these imperfections in my project that the patterns never seemed to have. Now I know better, blocking is the magic trick that I was missing! Don’t make the same mistake and give it a try.

Using a handmade blocking mat

It’s a very easy process. Take your project and soak it in some water. After the soak, get as much water out as possible but don’t squeeze your coaster! Roll it between 2 clean towels to get the water out. Lay it flat on your blocking mat.

If, like me, you don’t have a proper blocking mat, no problem, you can make one yourself. You just need a clean towel and some foam or anything soft you can prick into and that doesn’t get damaged by water (so no cardboard). You can even use a mattress or your couch. Pin the towel stretched to the foam (not too loose) and you’re good to go. For the pins, it is harder to go homemade. I tried to use my husband’s nails. That was a very bad idea. They rusted and destroyed my project. For a few bucks, you can get nice stainless steel T pins which you can easily reuse for each project.

Now you need to pin the edges of your coaster following a 10 cm diameter circle.

Let the crochet coaster dry as long as it needs. It needs to be 100% dry. Mine took 24-36h to dry entirely because it is very humid where I live.  Be patient! Now that it’s dry, remove the T pins, get yourself a nice cold drink and enjoy your coasters.
