The Midnight Diamond Blanket: A Tapestry Crochet Pattern Inspired by Decorative Tiles

This post was originally published in 2019 and has been fully updated in April 2026.

The Midnight Diamond Blanket is one of my oldest designs, and by some distance my most popular. It has been made by thousands of crocheters across the world, and I still feel genuinely pleased every time I see a new version appear on Instagram. It’s the kind of design that seems to connect with people immediately, which is always a lovely thing to witness.

In this post, I share the full story of the blanket – where the idea came from, how it works, and what to expect if you’d like to make one yourself.

The pattern is available on Etsy and Ravelry.

Where the Idea Came From

The design was inspired by decorative tiles. I’d been looking at photographs of patterned tiles and was drawn to the way a repeating geometric motif can create something much larger and more complex-feeling than any individual piece suggests. I wanted to recreate that quality in crochet, using tapestry crochet squares that would form a continuous pattern across the whole blanket once joined together.

The name came naturally. The diamond shapes within the squares, combined with the deep navy yarn I used (Stylecraft Special DK in Midnight), gave it a rich, slightly dramatic quality that felt right.

What the Blanket Looks Like

Each square features four diamonds radiating out from the centre, enclosed by curved lines. When 20 squares are joined together, those lines continue across the joins, creating a tile-like pattern that runs over the whole blanket. The effect is quite striking, and the design looks best in two strongly contrasting colours – one dark, one light – so the geometric pattern really shows up clearly.

The finished blanket measures 88 cm by 113 cm when made in DK yarn, which is a generous lap or throw size. Because the design is made from individual squares, you can also adjust the size relatively easily by adding or removing squares, or by working in a different yarn weight.

The Tapestry Crochet Technique

Tapestry crochet is a colourwork technique where two colours of yarn are carried together as you work, with whichever colour isn’t in use being carried inside the stitches. The result is a fabric that shows the pattern cleanly on both sides, with no floats or loose strands.

I find it one of the most satisfying techniques to work with. There’s a rhythm to it once you get going, and the way a clear pattern builds from what feels like quite a simple process still gives me a lot of pleasure. One thing I always mention to people new to tapestry crochet: the fabric is denser than standard crochet, which actually works well for a blanket – it gives it a lovely weight and warmth.

The Midnight Diamond is a good first tapestry crochet project. The stitch repeat is contained within each square rather than running across the whole blanket, which makes it easier to follow and to check your progress. The pattern includes a chart as well as full written instructions, and I’ve also linked to video tutorials for the key techniques – including managing the two yarns, ending rounds, and joining the squares.

Pattern Details

• Yarn: DK weight. The original is worked in Stylecraft Special DK in Cream (5 x 100g balls) and Midnight (2 x 100g balls). Any good DK will work – the blanket also works well in aran weight if you’d prefer something chunkier.
• Hook size: 3.5 mm (though as always, use whichever hook helps you meet gauge)
• Finished size: 88 cm x 113 cm in DK (approx. 34.5″ x 44.5″)
• Construction: 20 squares, each approx. 20.5 cm, joined together
• Skill level: Intermediate – suitable for someone confident with basic stitches who would like to try tapestry crochet for the first time
• Terminology: Available in both UK and US crochet terms
• What’s included: Full written instructions, a chart, pattern notes, photos, and links to video tutorials for key techniques

Colour Choices

The classic combination of cream and navy is the one I use most in my own work and teaching, and it remains popular for good reason – the contrast is clean and the result looks striking in most settings. That said, the blanket works in almost any two-colour pairing. I’ve seen it made in warm terracotta and white, soft grey and blush, bold black and yellow, and many others. If you’d like some guidance on choosing colours for tapestry crochet, the key factor is contrast: the bigger the difference in value (lightness versus darkness) between your two colours, the more clearly the pattern will read.

A Pattern with a History

I originally designed and released the Midnight Diamond in 2019. Since then, it has become my bestselling pattern, with nearly 3,000 copies sold. Earlier this year, I also had the pleasure of teaching it as a four-week in-person course at the Hive Design Studio in Surrey – it was really lovely to see people working through the squares together and watch the blankets come to life. And in early 2025, That Yarn Place, a yarn shop in Australia, chose it as their makers club project – it was a pleasure seeing their finished blankets appear from the other side of the world.
