If you love crochet projects that look impressive but don’t require complicated stitches, this Mosaic Diamonds Crochet Blanket is definitely worth adding to your to-do list. The diamond design gives it a lovely modern look, while the combination of two coordinating yarn colors creates a beautiful pattern with plenty of depth and texture.
Mosaic crochet is one of those techniques that can look a little intimidating at first, but once you get comfortable with the stitches, it becomes surprisingly enjoyable. The secret behind this blanket is the mosaic double crochet, which creates the raised diamond shapes and makes the whole design stand out.
I especially love how the self-striping yarn works alongside a solid shade. The colors blend together beautifully, giving the blanket an almost woven appearance without having to change colors constantly.
Whether you’re making something cozy for your own home or preparing a handmade gift for someone special, this blanket is a lovely project to spend your time on.
Materials You’ll Need
Before getting started, gather the following supplies:
- Yarn: Caron® Colorama Halo™ (Bulky 5)
- Color A: After the Rain Stripes (06012) – 4 balls (1,530 yds / 1,393 m)
- Color B: Cream (06002) – 3 balls (1,290 yds / 1,174 m)
- Crochet hook: U.S. J/10 (6 mm) Susan Bates® Silvalume® crochet hook
- Tapestry needle for weaving in ends
- Scissors
Finished Size and Gauge
The finished blanket measures approximately 54 x 62 inches (137 x 157.5 cm), making it a comfortable size for draping over a sofa, adding to your bed, or curling up with on a chilly evening.
Gauge: 12 single crochet stitches and 14 rows measure 4 inches (10 cm).
Taking a moment to check your gauge before starting will help you get a finished blanket close to the intended measurements.
Special Stitch: Mosaic Double Crochet
The main stitch that gives this blanket its distinctive diamond pattern is the Mosaic Double Crochet (Mosaic Dc).
To make it, work a double crochet into the skipped single crochet stitch three rows below, placing the stitch in front of the chain spaces.
This technique creates the lovely overlapping effect that makes mosaic crochet so interesting. It may take a little practice, but after a few repeats, you’ll get into a comfortable rhythm.
A Few Helpful Notes Before You Begin
Here are some details worth keeping in mind as you work through the pattern:
- Each skipped single crochet has chain spaces worked above it for two rows. These spaces leave room for the mosaic double crochet in a later row.
- Chain-2 spaces count as one stitch.
- Always work the mosaic double crochet in front of the chain spaces.
- Carry the unused yarn loosely up the side of your work.
- The starting chain is worked in multiples of 12 + 16.
Keeping these points in mind will make following the pattern much easier.
Mosaic Diamonds Crochet Blanket Instructions
Starting Chain
Using Color A, chain 160. This follows the required multiple of 12 + 16.
Setup Rows
Row 1: Single crochet in the second chain from the hook and in every chain across. You should have 159 single crochet stitches. Turn.
Row 2: Chain 1, then work a single crochet in every stitch across. Turn.
Main Mosaic Pattern
Now it’s time to begin the diamond design!
The main pattern is worked over a 24-row repeat, alternating between Color A and Color B. You’ll use single crochet stitches, chain-2 spaces, and mosaic double crochet stitches to build the geometric design.
Follow the established stitch placement throughout each row, remembering to work the mosaic double crochets in front of the chain spaces.
Continue repeating Rows 1–24 until your blanket measures approximately 62 inches (157.5 cm), finishing with Row 24.
Fasten off when you’ve completed the pattern.
Note: The original instructions provided here describe the 24-row repeat but do not include the individual stitch-by-stitch instructions for those 24 rows. You’ll need the complete pattern chart or original instructions to reproduce the exact diamond layout.
Adding the Side Edging
A simple edging gives the blanket a neat, finished appearance.
With the right side facing you, join Color A with a slip stitch in one corner.
Chain 1, then work single crochet stitches evenly along the side edge. As you go, make sure to enclose the carried yarn so it stays neatly hidden.
Fasten off and repeat the same process along the opposite side.
Weave in any remaining ends with your tapestry needle.
Color Ideas to Make It Your Own
One of the nicest things about this pattern is how easily you can change its personality just by choosing different yarn colors.
Here are a few combinations I’d love to try:
- Modern Minimalist: Charcoal gray and cream for a clean, contemporary look.
- Boho Glow: Mustard yellow and coral pink for a warm, cheerful combination.
- Ocean Mist: Teal and ivory for a calm, coastal feel.
- Classic Comfort: Beige and navy blue for a timeless combination.
Don’t be afraid to experiment with your yarn stash. Sometimes an unexpected color combination turns into a favorite!
