Cozy Diamond Lattice Blanket & Pillow Set Crochet Pattern

Introduction

If you are searching for a bold and sophisticated statement piece to add warmth and personality to your bedroom, this crochet diamond lattice blanket and pillow set is the perfect project. Rich burnt orange and soft cream work together in textured, almost sculptural motifs that come together to form a striking pattern. Each motif features a repeating diamond or fan appearance, set off by subtle dark accent stitches at the connecting points. The finished effect is dramatic, eye-catching, and deeply cozy—ideal for a fall or winter décor refresh or as a thoughtful handmade gift.

This set includes a large, plush throw blanket and two matching pillows, making it not just a practical addition for warmth, but also a showpiece that elevates any bedroom’s style. The texture and dimensionality of the motifs make this pattern fun to create—even more so when you see the growing blanket wrap your bed in vibrancy and softness. If you love projects that combine interesting geometric patterns, inviting fibers, and a pop of color, you’ll enjoy working through and displaying this beautiful crochet set.

Project Overview

The diamond lattice blanket and pillows are constructed by crocheting individual motifs—each shaped like a diamond or fan with alternating stripes of burnt orange and cream. These motifs are joined together as you go, or can be sewn upon completion, creating a strong and seamless grid. The motifs are arranged in rows and columns, with side and top edges squared off for a neat finish. The pillow covers use the same motif, forming rectangles to fit standard pillows. Optional: add a border around the blanket for an extra-polished look.

Skill Level

Intermediate: This project is perfect for those who are comfortable with basic crochet stitches, color changes, and working in the round. Some experience with motif construction and join-as-you-go techniques is helpful, though adventurous advanced beginners could certainly tackle it with patience.

Materials

Worsted weight (category 4) yarn in two colors (Color A: Burnt Orange, Color B: Cream), plus a small amount of black or deep brown yarn for accent dots.
Approximate yarn amounts for a blanket 155 x 200 cm (61 x 79 in):
- Color A (Burnt Orange): 1300 g (about 2520 yds / 2304 m)
- Color B (Cream): 1100 g (about 2130 yds / 1948 m)
- Accent (Black/Brown): 50 g (about 100 yds / 91 m)
Suggested fiber: 100% acrylic, wool-acrylic blend, or superwash wool for durability and easy care
Crochet hook size: 5.0 mm (H-8)
Tapestry needle for weaving in ends and joining motifs
Scissors
Stitch markers (optional, for tracking motif placement)
Measuring tape

Finished Size

Blanket: Approx. 155 cm x 200 cm (61 x 79 inches) – easily adjustable by adding or subtracting motifs. Each single motif measures about 11 x 11 cm (4.3 x 4.3 inches) when blocked. Pillow covers: Made to fit 50 x 70 cm (20 x 28 in) standard pillows. To resize, adjust the number of motifs joined across and down or use a different yarn weight.

Gauge

One complete motif should measure approximately 11 x 11 cm (4.3 x 4.3 inches) after blocking. Gauge is not critical but will affect overall size and yarn usage; make a test motif and adjust hook size if necessary. For even texture, keep tension consistent throughout.

Stitches and Abbreviations

ch – chain
sl st – slip stitch
sc – single crochet
hdc – half double crochet
dc – double crochet
tr – treble crochet
MR – magic ring
inc – increase (2 st in same space)
sp – space
st – stitch
rep – repeat

Pattern Notes

Work motifs in joined rounds; ch 3 at the start of a round counts as a dc unless otherwise stated.
Change colors at the end of rounds by finishing the final yarn over with the new color, for neat transitions.
Right side (RS) always faces out as you join motifs; this keeps texture consistent.
Motifs can be joined as you go on the final round, or sewn together afterward with whipstitch or mattress stitch.
To minimize weaving in ends, crochet over tail yarns when possible.
Use stitch markers to help orient motifs or to mark the edges for even joining.

Crochet Pattern Instructions

Motif (make as many as needed for blanket and pillows)

With Color A (Burnt Orange), make a MR. Ch 3 (counts as dc), 3 dc into ring, ch 2, *4 dc into ring, ch 2; rep * twice more (total 4 sets). Tighten MR and join to top of beg ch-3 with sl st. (16 dc, 4 ch-2 sps)
Sl st to next ch-2 sp. Ch 3, 2 dc in same sp, ch 2, 3 dc in same sp (corner made), ch 1, *(3 dc, ch 2, 3 dc) in next ch-2 sp, ch 1; rep from * twice more, join to top of beg ch-3. (24 dc, 4 ch-2 corners, 4 ch-1 sps)
Switch to Color B (Cream). Sl st to ch-2 corner sp, ch 3, 2 dc in same sp, ch 2, 3 dc in same sp, ch 1, 3 dc in next ch-1 sp, ch 1, *[(3 dc, ch 2, 3 dc) in ch-2 corner sp, ch 1, 3 dc in next ch-1 sp, ch 1]; rep * twice more, join. (40 dc)
Continue alternating Color A (Burnt Orange) and Color B (Cream) each round:
- Round 4 (Color A): Sl st/attach to corner, ch 3, 2 dc, ch 2, 3 dc in corner, [ch 1, 3 dc in next ch-1 sp, ch 1] twice, rep for each side. Join. (56 dc)
- Round 5 (Color B): Work as above, placing (3 dc, ch 2, 3 dc) in corners and 3 dc in each ch-1 sp, separated by ch 1. (72 dc)
- This creates a growing square motif with diamond/fan visual effect on diagonal. Stop after 5 rounds for 11 x 11 cm motif.
For accent dot, use black (or brown). Attach in center of each motif with needle, embroider a small French knot or sew a small round of slip stitches in the center for added visual pop.

Join Motifs for Blanket

Lay out motifs in desired grid: approximately 14 motifs across x 18 down for a 155 x 200 cm blanket.

Use whipstitch, mattress stitch, or join-as-you-go sl sts (through corner and edge ch-sps) to attach motifs, making sure diamond pattern lines up diagonally for the lattice look.

Pillow Covers

Make a rectangular grid – for a 50 x 70 cm pillow, use motifs 5 across x 7 down (adjust to fit).
Assemble front and back rectangles. (For a removable cover, make two rectangles; for a sewn edge pillow, make one rectangle and fold.)
Stitch together, leaving an open edge or section for pillow insertion; add decorative buttons, zipper, or simple envelope fold as preferred.

Optional Blanket Border

Using Color A, join yarn in any corner. Work sc evenly around, placing 3 sc in each corner. Join and fasten off.
Work additional rounds in alternated colors if desired.

Assembly and Finishing

Once all motifs are complete and joined, lay the blanket and pillow covers flat and gently shape edges with your hands. Weave in all ends with a tapestry needle, ensuring that color changes are secured and the stitches lay flat. If motifs have curled during joining, lightly block the blanket by pinning it out to size and spraying with water or using steam (check your yarn’s fiber content first). Allow to dry completely before removing pins. For pillows, insert forms after weaving in ends and securing all seams.

Customization Ideas

Switch up the colors for a more subtle or bold effect; try cool tones, neutrals, or jewel shades.
Use a chunky yarn for an oversized, squishier blanket, adjusting hook size and motif count.
Make a baby blanket or throw by reducing the number or size of motifs.
Use scrap yarn for a colorful, one-of-a-kind patchwork look.
Add pom-poms, tassels, or fringe to the edges for extra flair.

Troubleshooting

If your motifs curl or ruffle, check that your tension is not too tight and that stitch counts are consistent at corners.
Uneven edges may stem from inconsistent joining; use markers and always line up corner stitches exactly.
If the blanket is too large or too small, adjust by making fewer/more motifs or using a different hook size.
Loose or untidy color changes can be improved by carefully finishing each round, pulling new color through the last yarn over, and weaving in ends.
Tension differences sometimes develop over the course of a big project—take breaks and check regularly by stacking motifs to confirm they remain uniform.

Care Instructions

Machine wash finished blanket and pillow covers on a gentle cycle in cold water, using a mild detergent. Lay flat or tumble dry low. Avoid ironing unless using steam to gently block. Store folded or draped to avoid stretching edges.

Final Notes

Always check your stitch counts at the end of each motif round and when joining, to maintain the neat lattice pattern. Adjust your hook size if motifs appear too tight or loose. Refer to the project photo as a guide for color placement and motif orientation. With patience and attention to detail, you’ll create a truly stunning and durable heirloom set.
