How to Make a Mosaic Crochet Blanket: The Thassos Pattern

6 August 2020 by Sylwia (MyCrochetory) 7 Comments

Updated: 2 November 2026 by Sylwia (MyCrochetory)

One yarn at a time and a few simple stitches. That’s really all this mosaic crochet blanket needs for its black and white zigzags.

The design is one repeat of stepped lines and tall white shapes, worked again and again across the blanket. After the first repeat you start to see where the next line goes, and the rows get easier.

Mosaic crochet was my favorite technique when I designed the Thassos Blanket, and it’s still one of my top ones today. I named the blanket after Thassos, a Greek island known for its white marble.

Black on white looks great in a white, minimalist room. But it also works with wood, gray or bright colors, because two plain colors match almost anything.

I’ll start with how the technique works and how I block the finished blanket. Then you get the free pattern with written rows, a chart, a video and photos of the key rows.

Jump to the Thassos Mosaic Blanket free pattern, or get the ad-free printable PDF with the chart and a stitch tracker on Etsy or on Ravelry.

Where This Black and White Mosaic Crochet Blanket Came From

This mosaic crochet blanket started with a wrap. I was in my mosaic phase back then, working on my Monochrome Bias Wrap, and I already knew my next project would be a black and white blanket.

Black and white is the strongest contrast you can get. Every line of the pattern shows, even when the blanket is lying on the sofa across the room.

Not sure about choosing colors for colorwork? Two colors is the easiest way to start. Any light and dark pair works, so go with colors you’d actually want in your home.

How Mosaic Crochet Works in This Blanket

You only work with one color at a time in this blanket. Two rows in white, two rows in black, and you change colors in the last stitch of every second row.

On right side rows, you make chains over the stitches you skip. Two rows later you come back to those skipped stitches with a mosaicdc, worked in front of the chains, and these long double crochets build the pattern.

Wrong side rows are just single crochet and chains, so they go quickly. You hold only one yarn, and nothing runs across the back of your work.

Is This Mosaic Crochet Blanket Hard to Make?

The level is intermediate, mostly because you have to count your stitches. If you’ve ever crocheted stripes in two colors, you already know every stitch in it.

What about the ends? You don’t cut the yarn at the color changes, you just carry it up the side. So even after almost 200 rows, you only have a few ends to weave in.

If mosaic is new to you, my mosaic crochet in rows tutorial is a good place to practice first. It shows a small swatch with the same color changes every 2 rows.

And if long starting chains aren’t your favorite part, you can begin the blanket with a foundation single crochet row instead.

Yarn for This Mosaic Crochet Blanket

I made this mosaic crochet blanket in Gazzal Baby Cotton XL, a DK weight yarn with 50% cotton and 50% acrylic. The stitches come out clear and neat, so you can see the pattern well.

I still recommend this yarn for the pattern. You’ll need 10 balls of white and 8 balls of black, and the blanket comes out about 35.5 by 40.5 inches.

That’s a nice size to keep on the sofa, and it works as a baby blanket too.

How I Steam Block This Mosaic Crochet Blanket

The yarn is a cotton blend, so I block this blanket with steam. I pin it flat to the right size and hold my steam iron about 1/2 inch above it, without touching the fabric.

Then I leave it pinned for at least 20 minutes, but no longer than an hour. When I take the pins out, the edges are flat and the lines are nice and straight.

Materials & Tools

  • Yarn: Gazzal Baby Cotton XL, DK weight (50% cotton, 50% acrylic, 50 g = 105 m / 115 yd).

Yarn A: White (3432), 10 balls, about 1050 m (1148 yd).

Yarn B: Black (3433), 8 balls, about 840 m (919 yd).

Yardage may vary with your yarn, gauge or changes to the size.

  • Hook: 4 mm. Adjust the hook size if necessary to obtain the correct gauge.
  • Tapestry needle (to weave in the ends).
  • Scissors.

Level

Intermediate.

Gauge

15 sts and 19 rows = 10 x 10 cm (4 x 4″) in sc with a 4 mm hook.

If necessary, adjust the hook size to get the correct gauge.

Size (adjustable)

About 90 x 103 cm (35.5″ x 40.5″).

General Notes

  • The pattern uses US crochet terms.
  • The blanket is worked flat, in rows back and forth, in mosaic crochet.
  • The width is a multiple of 22 plus 1 st (start with a multiple of 22 plus 2 chains). To make the blanket wider or narrower, add or remove 22 chains.
  • For the length, work more or fewer repeats of Rows 5–68.
  • Ch1 at the beginning of each row doesn’t count as a st.
  • You can use a different yarn weight, but the size of the blanket will change with your gauge.
  • STITCHES: When you see a stitch followed by a number, e.g. sc14, work 1 sc into each of the next 14 sts. When you see a number followed by a stitch, e.g. 2sc, work 2 sc into the next (same) st.
  • Instructions in […] and *…* are worked as many times as indicated.

Mosaic Crochet Notes

  • Follow the written rows or the chart, whichever you like.
  • Change color every 2 rows, in the last st of the row.
  • Don’t cut the yarn. Carry the other color up the side and pick it up again when you need it.
  • You only work with one color at a time.

How to Read the Mosaic Chart

  • The chart is read from bottom to top, and each row of squares is 2 rows worked in the same color.
  • RS rows (odd numbers: 1, 3, 5…) are read from right to left.
  • WS rows (even numbers: 2, 4, 6…) are read from left to right.
  • Each square is 1 stitch or 1 skipped stitch.
  • A square in the color of the current row means sc.
  • A square in the other color means you skip that stitch and make chains instead. To prevent puckering, chain 1 more than you skip: ch2 for 1 skipped st, ch4 for 3, ch8 for 7.
  • Count the skipped stitches carefully on RS rows.
  • On WS rows, work sc in every st without missing any.
  • On the next RS row of the same color, work mosaicdc into the skipped sts from 2 rows below. Mosaicdc are always worked in front of the chains.
  • IMPORTANT! Mosaicdc are always worked on RS rows. WS rows have only sc and chains.

Stitches & Abbreviations (US terms)

ch(s) – chain(s) stitch

ch-sp – chain space

st(s) – stitch(es)

sc(s) – single crochet

dc(s) – double crochet

slst – slip stitch

mosaicdc (mosaic double crochet) – work regular dc in unworked/skipped st of the same color two rows below in front of chain space (in front of work). These chains will stay behind mosaicdc and will stay unworked.

sp – space

sk – skip

beg – beginning

prev – previous

RS – right side

WS – wrong side

rep – repeat

Fsc – foundation single crochet

Mosaic Crochet Blanket FAQ

What yarn can I use for this mosaic crochet blanket?

Any DK weight cotton or cotton blend works well. Pick two colors with strong contrast and check your gauge first, since a different yarn changes the size of the blanket.

How do I make the blanket bigger?

Add 22 chains to the starting chain for each extra repeat in width. For more length, repeat Rows 5–68 again before you work the last rows.

Why is my mosaic crochet puckering?

Usually the chains over the skipped stitches are too short. Chain 1 more than the number of stitches you skip, and don’t pull the chains tight.

Do I need the chart to follow the pattern?

No, every row is written out in full. The chart shows the whole design at a glance, so use whichever one you find easier.

    Is there supposed to be a chart for this pattern? I don’t see it anywhere on this page. I love this style of mosaic crochet (and love this pattern), but sometimes find a chart to be very helpful.

    I’ve never tried mosaic crochet before, but I think I can do this, as your instructions seem to be “spot on”. Thank you for a beautiful pattern!
