About This Color Block Square Crochet Coasters Pattern

This pattern teaches you to crochet a color block square coaster built from a central 3-round square and four added rectangular color sections. You'll switch yarn colors as you go to create a neat patchwork look. It's a quick, satisfying make that showcases cotton yarn texture and color gradients beautifully.

Why You'll Love This Color Block Square Crochet Coasters Pattern

I absolutely love this pattern because it turns simple double crochet clusters into a stylish color-block coaster with minimal effort. I enjoy how quickly each coaster grows — you can complete one in an afternoon. The method of joining sections while crocheting keeps finishing to a minimum, which is so satisfying. I also love that it uses small amounts of five different colors, perfect for using up leftover yarn and creating beautiful, coordinated sets.

Switch Things Up

I love experimenting with color for this pattern: try pastel shades for a soft, shabby-chic coaster set or bright contrasting colors for a modern look.

You can make the coasters larger or smaller by changing your yarn weight and hook size; a bulky yarn with a larger hook will produce a thicker, chunkier coaster.

I often add a simple single crochet border in a neutral color to frame the coaster and hide any uneven edges.

For a more rustic finish, use natural-colored cotton or linen-blend yarn and a slightly larger hook to soften the texture.

If you want a set that coordinates with your kitchen, pick five colors from the same yarn line like the Hobbii Rainbow shades used here.

I sometimes embroider a small initial or motif on the center square for personalization and to make a thoughtful gift.

Consider making matching cup cosy or placemats by adapting the pattern size and repeating the color-block sections across a larger surface.

I like to block each coaster lightly after finishing to ensure straight edges and a professional look.

Try alternating the order of the colored sections so each coaster in a set has a different layout for a playful, mixed set.

If you want to minimize ends, experiment with carrying colors along the back where possible or use a running stitch join instead of cutting yarn between sections.

Common Mistakes & How to Fix Them

✗ Trying to use a much larger hook than recommended will produce a floppy coaster; use the suggested 2.0 mm hook or adjust yarn weight carefully to keep the stitches close and the coaster firm. ✗ Not counting chains when starting the rectangular sections can misalign the edges; count your chains carefully and place the 3 Dc groups in the correct chain spaces to maintain a straight edge. ✗ Changing colors without securing tails can cause loose ends and gaps; leave a short tail and weave in ends securely or carry the yarn neatly at the back when possible. ✗ Working too loosely on the double crochet clusters creates gaps between clusters; keep a consistent, slightly firm tension so the texture of the clusters remains even and the coaster lies flat.

Ch: Chain. Sst: Slip stitch. Dc: Double crochet.

— Size :

Info :

the coasters will have an estimated finished size of 11 x 11 cm (approximately 4.3 x 4.3 inches). Different yarns may result in slightly different sizes.

— Instructions :

Info :

Start with yarn A. Rows 1 to 3 will complete the following section (shaded) of the coaster:

Round 1 :

On a magic ring Ch 3 (counts as a double crochet plus a one chain) and then add the following: 3 Dc, Ch 1, 3 Dc, Ch 1, 3 Dc, Ch 1, 2 Dc. Sst to join.

Round 2 :

Ch 3 (counts as a double crochet plus a one chain) and then add 3 Dc on the corner chain space from the previous row. In each of the other three corners, add the following: 3 Dc, Ch 1, 3 Dc. Finish the row adding 2 Dc in the same corner chain space where you started, and Sst to join.

Round 3 :

Ch 3 (counts as a double crochet plus a one chain) and then add 3 Dc on the corner chain space from the previous row. Add 3 Dc in the middle of the side of the square (over the space between the double crochet clusters from previous row). *In the next corner, add the following: 3 Dc, Ch 1, 3 Dc, and then 3 Dc in the middle of the next side of the square.* Repeat the pattern between * two more times. Finish the row adding 2 Dc in the same corner chain space where you started, and Sst to join.

Info :

Now switch to Yarn B and you are going to work on the following section (shaded) of the coaster:

Round 4 :

Starting on one of the corner spaces of the previous section of the coaster, Ch 11: Add 3 Dc in the third chain from hook, skip three chains, add 3 Dc in the following chain, and finally 3 Dc in the corner space from the previous section of the coaster (the same space where you started your chain).

Round 5 :

Turn your work around. Ch 1, then add 3 Dc over the next space from previous row. Continue until the end of the row adding 3 Dc over each of the spaces from the previous row. Add one final Dc over the last stitch from previous row:

Round 6 :

Turn your work around again and add 3 Dc over each of the spaces from previous row (including the first one and the last one-chain space from where you started the previous row):

Round 7 :

Turn your work around again. Ch 1, then add 3 Dc over the next space from previous row. Continue until the end of the row adding 3 Dc over each of the spaces from the previous row. Add one final Dc over the last stitch from previous row. Cut the yarn and this section of the coaster is done. By now your coaster will look like this:

Info :

Now switch to Yarn C and you are going to work on the following section (shaded) of the coaster:

Round 8 :

Start at the edge of the Yarn B section you have just completed and Ch 2, as shown below: Add 2 more Dc in the same space, and then continue the row with 3 Dc over each of the spaces of the row below:

Round 9 :

Turn your work around. Ch 1, then add 3 Dc over the next space from previous row. Continue until the end of the row adding 3 Dc over each of the spaces from the previous row. Add one final Dc over the last stitch from previous row:

Assembly Instructions

  • Weave in all yarn ends securely on the back of the coaster using a yarn needle, trimming excess yarn once finished.
  • Block the coaster lightly if desired to flatten edges: dampen gently and pin to shape on a blocking mat until dry.
  • When joining the final Yarn E section to Yarn B, ensure the chain is grabbed as indicated to make a neat join; check that edges align before finishing the row.
  • Trim any loose loops and check corners for even 3 Dc cluster placement, adjusting tension if necessary.

Important Notes

  • 💡A 2.0 mm hook was used for the coasters to keep the stitches closer together; using the recommended 2.5–3.5 mm hook range will produce a slightly larger and looser coaster.
  • 💡Work with consistent tension throughout to ensure even cluster texture and a flat finished coaster.
  • 💡Cut yarn and weave ends after finishing each colored section to keep the coaster tidy and prevent long tails showing on the right side.

These color block square crochet coasters are a quick and rewarding project that brightens any table. Make a set in coordinated shades or mix contrasting hues for a bolder look. Perfect for gifting, swapping scrap yarn, or adding handmade style to your home. 🧶🫖
