Diagonal Stone, a Beautiful Diagonal Crochet Blanket to Make

Updated: 11 November 2026 by Sylwia (MyCrochetory)

Most blankets start with a long chain and grow straight up, row after row. This diagonal crochet blanket starts in one corner with just 5 stitches and grows on the slant until it reaches the opposite corner.

That shape was simply an idea I wanted to play with. I’ve always been drawn to shapes, and I wanted to see what plain stripes would do in a rectangle crocheted on the diagonal.

They run across the whole blanket at an angle, and that’s the fun of it. Wide bands of double crochet swap with open rows of 3-dc groups, in soft pink and cream.

The yarn gave the blanket its name, Scheepjes Stone Washed XL. It’s an aran weight, so the stripes add up quickly.

How a diagonal crochet blanket grows

Here’s the funny part. For most of this diagonal crochet blanket, the stitch count doesn’t change at all.

First you increase at both edges, so you get a triangle that grows with every row. Then, in the long middle part, one edge increases and the other decreases, so you stay at 177 dc while the blanket gets longer.

At the end you decrease at both edges until the last corner closes. No seams, no squares to join, just one piece from corner to corner.

Diagonal crochet blanket stripes in double crochet and granny shells

My very first crochet project was a granny square blanket for my daughter. Those little 3-dc groups are back here, only now they’re worked in rows on the diagonal.

They swap with solid rows of double crochet. The solid rows build the wide stripes of this diagonal crochet blanket, and the 3-dc groups with ch-1 spaces between them make the open bands.

The open rows go fast, and they make the blanket a little lighter too.

The color sequence of the diagonal crochet blanket

Look closely and you’ll see that some stripes are only one row thin. The colors follow one 22-row sequence through the whole diagonal crochet blanket, with wide pink bands, thin pink lines and cream stripes in between.

You’ll never have to guess which yarn comes next, because the stitch count table in the pattern shows the color of every row. Want your own colors? Pick two with strong contrast, or the thin lines will disappear.

The last corner of your diagonal crochet blanket

After more than a hundred rows, the whole blanket closes with one single cluster. It’s four tall stitches worked together over the last stitches, and there’s a step-by-step photo tutorial for it below.

Then a simple border runs all the way around, with dc2tog and 2 dc, plus 3 dc in each corner. Pink gives you a clear frame, and cream gives a softer edge.

Yarn and blocking for your diagonal crochet blanket

I made my diagonal crochet blanket in Scheepjes Stone Washed XL, a cotton and acrylic aran yarn, and I still recommend it. You’ll need 12 skeins of pink and 11 of cream, about 984 and 902 yards.

Yarn substitutes

Stone Washed XL is sold out at LoveCrafts right now, so here’s what I’d swap in. Paintbox Yarns Cotton Aran is a 100% cotton aran with 93 yards in a 50 g ball, and it comes in loads of pinks.

It’s a little thinner than Stone Washed XL and has no acrylic, so the blanket comes out slightly smaller and firmer. Get 11 balls for Yarn A and 10 for Yarn B, and Dusty Rose with Vanilla Cream gets you close to my colors.

A blanket this big is a pain to soak and dry, and with cotton blends I don’t need to. I pin the blanket to a mat, hold a hot steam iron about half an inch above it without touching, and leave it pinned for at least 20 minutes.

The finished blanket is about 34.25 inches wide and 61 inches long. That’s big enough to curl up under on the couch.

Stitch count with color scheme

Color sequence: Yarn A is Rose Quartz (pink) and Yarn B is Pink Quartzite (cream). Work Rows 1–4 with Yarn B, Row 5 with Yarn A, Rows 6–7 with Yarn B, Row 8 with Yarn A, Rows 9–12 with Yarn B and Rows 13–22 with Yarn A. Repeat this 22-row sequence 4 more times (Rows 23–110), then work Rows 111–122 like Rows 1–12. (In the table above the shaded rows are Yarn A and the white rows are Yarn B. Row 79 has 173dc, 2 ch-1 sp.)

Border

Pick either yarn A or yarn B and start doing the border.

Attach the yarn in the corner and make ch3, 2dc in the same corner/stitch, [dc2tog (first leg around the same corner/stitch, second leg around next space here and throughout), 2dc in the same space where second leg of dc2tog is placed] repeat around – instead of 2dc make 3dc in each corner. Slip stitch in the 3rd chain of beg ch3.

Corner cluster tutorial

Yarn over twice and insert the hook in the specified stitch (the arrow points at the right stitch), yarn over and pull through, yarn over and pull through 2 of 4 loops already on the hook, yarn over and pull through 2 of 3 loops already on the hook. Do not complete the stitch – 2 loops on the hook.

Yarn over twice and insert the hook in the next stitch, yarn over and pull through, yarn over and pull through 2 of 5 loops already on the hook, yarn over and pull through 2 of 4 loops already on the hook. Do not complete the stitch – 3 loops on the hook.

Yarn over twice and insert the hook in the next stitch, yarn over and pull through, yarn over and pull through 2 of 6 loops already on the hook, yarn over and pull through 2 of 5 loops already on the hook. Do not complete the stitch – 4 loops on the hook.

Yarn over twice, skip next ch1 and insert the hook in 3rd chain of ch4 at beg of prev row, yarn over and pull through, yarn over and pull through 2 of 7 loops already on the hook, yarn over and pull through 2 of 6 loops already on the hook. To complete the stitch yarn over and pull through 5 loops on the hook.

Make a slip stitch and start doing the border or fasten off the yarn and pick another color and make a border.

Fasten off yarn, weave in all ends and block your blanket.

Diagonal crochet blanket FAQ

Is this diagonal crochet blanket good for beginners?

It’s an intermediate pattern, but the stitches are simple, mostly double crochet and ch-1 spaces. If you can increase and decrease at the edges, you can make it.

Can I make the blanket bigger or smaller?

For a longer blanket, work more rows in the middle section, in pairs of Rows 45 and 46. The width comes from the first section, so for a smaller or bigger blanket overall, the easiest way is a thinner or thicker yarn with a matching hook.

How do I keep the colors straight?

Follow the stitch count table, which shows the color for every row. Some stripes are just one row, so cut the yarn at each color change and weave in the ends as you go.
