The contrast between the reds and creams creates a visually striking patchwork that will spark conversation and admiration, making this a memorable gift or a proud accomplishment for your own home.
Project Overview
This geometric crochet blanket is made up of individual granny square motifs, each worked in the round from the center outward, then joined together in a diamond-based layout. Every square alternates between red and cream sections to create an illusion of interlocking patterns. The squares are edged and then joined by sewing or crocheting together. Once assembled, the blanket is finished with a clean border for a polished look. The modular construction makes adjustments and color changes straightforward, while pillow covers follow the same motif for coordinated décor.
Skill Level
Intermediate. This project is best for crafters with some experience in colorwork and granny square construction. Skills required include color changes, working in the round, joining motifs, and maintaining an even tension for a professional finish.
Materials
- Yarn: DK (light worsted, weight 3) acrylic or cotton blend; amount depends on desired finished size
- Cream/Off-white: 2,000–2,200 yd (1,830–2,010 m)
- Deep red: 1,000–1,200 yd (915–1,100 m)
- Burgundy/wine: 800–1,000 yd (730–915 m)
- Crochet Hook: US G/6 (4.0 mm) or size needed for gauge
- Tapestry needle (blunt tip for joining squares and weaving in ends)
- Scissors
- Stitch markers (optional, helpful for marking beginning of rounds or color changes)
- Blocking supplies (pins and blocking mat, optional but recommended for best shape)
Finished Size
The sample blanket in the image measures approximately 200 x 220 cm (78 x 86 inches), fitting a queen-size bed with ample drape. Each square is about 18 x 18 cm (7 x 7 inches) after blocking. To modify the finished size, add or subtract squares in width or length, or change the yarn weight and hook size for smaller/larger squares. Coordinated pillows use the same motif; adjust square count for your preferred pillow size.
Gauge
One completed square, blocked, should measure roughly 18 x 18 cm (7 x 7 inches). Gauge is approximately 17 dc and 9 rows = 10 cm (4 inches). Adjust hook size as needed for consistent squares. Small variations in gauge will affect the final measurements and overall fit of the blanket.
Stitches and Abbreviations
- ch – chain
- sl st – slip stitch
- sc – single crochet
- dc – double crochet
- tr – treble crochet
- MR – magic ring
- inc – increase (2 dc in same stitch)
- RS – right side
- WS – wrong side
Pattern Notes
Chains at the start of rounds count as stitches unless otherwise specified. Each granny square is worked in joined rounds; use a slip stitch to join at the end of each round. Change colors at the end of a round for neat transitions; fasten off and rejoin new color as needed. Always carry unused yarn loosely across the WS or use a separate ball for each section for tidiest color changes. Place a stitch marker in the first stitch of each round to help keep track when working the squares. For best results, block each square before joining to achieve uniform size and clean lines. The initial magic ring center ensures a tight, neat start to each motif.
Crochet Pattern Instructions
Center Motif
- Round 1 (Cream): MR, ch 3 (counts as dc), 2 dc in ring, *ch 2, 3 dc in ring; repeat from * two more times, ch 2, join with sl st to top of ch-3. (4 groups of 3 dc, 4 ch-2 corners)
- Round 2 (Cream): Sl st in next 2 dc and into corner sp, ch 3, (2 dc, ch 2, 3 dc) in same corner, *ch 1, (3 dc, ch 2, 3 dc) in next ch-2 corner; repeat from * twice more, ch 1, join with sl st to ch-3. (4 corners, 12 dc along each side)
Main Geometric Pattern
- Round 3 (Red): Join red in any ch-2 corner, ch 3, (2 dc, 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 corner; repeat from * around, join. (Each side: 3 granny groups + corner)
- Round 4 (Deep Red or Wine): Join in any corner, work (3 dc, ch 2, 3 dc) in corner, *ch 1, 3 dc in next ch-1 sp (twice), ch 1, (3 dc, ch 2, 3 dc) in corner; repeat from * around, join. At the end, fasten off.
Color Block Expansion
- Round 5 (Cream): Working in cream, join with sl st in a corner, (3 dc, ch 2, 3 dc) in corner, *ch 1, 3 dc in each ch-1 sp along side, ch 1, (3 dc, ch 2, 3 dc) in corner; repeat from * around, join.
- Round 6 (Red): As above, but alternate placement to create visual stripes (see note).
- Round 7 (Cream): As above, continue growing square, following visual guidance to alternate red and cream for L-shaped blocks radiating from the center and build up the geometric effect. If desired, work half the side in red, half in cream, and carry yarn as needed for crisp division.
- Round 8 (Deep Red): To intensify the color effect, work another color band along one or two sides, changing at corners as needed. Plan ahead for each square to position colors differently for secondary diamond patterns when blanket is assembled.
Edging
- Round 9 (Red): Work a final round of sc evenly around, placing 3 sc in each corner ch-2, and 1 sc in each stitch/space along sides. Join and fasten off. Block your square to 18 x 18 cm (7 x 7 inches).
Joining the Squares
- Lay out your motifs in a diamond formation, rotating as shown in the main image to form the larger geometric effect.
- Join squares using whip stitch with tapestry needle or crochet join (sl st or sc through both pieces) on the WS for neatest seams. Make sure color bands line up for seamless pattern flow. Weave in all ends securely on WS.
Border
- After all squares are joined, attach red yarn in any corner, *sc evenly around the blanket edge, placing 3 sc in each joining point or outer corner; repeat for 2–3 rounds, alternating cream and red as desired. Fasten off, weave in ends, and block entire blanket for a smooth, professional finish.
Assembly and Finishing
Once all squares are completed, lay them out flat to determine the best arrangement for your preferred pattern flow. Pin each square in place if needed, then join with whip stitch or single crochet, matching stitch counts carefully to prevent puckering. Use a new strand for each color edge you join to keep seams neat. For pillow covers, make two motifs and seam on three sides, inserting pillow form before closing last side. When all squares and edges are joined, weave in any remaining yarn tails on the WS.
Blocking is recommended for the finished blanket and individual squares. Pin the blanket to a blocking mat and spray lightly with water, then allow to dry completely to help even out stitches. For extra durability, use a yarn needle to anchor loose ends securely, especially if blanket will get heavy use. Smooth out the final border and let air dry flat to preserve shape. Display on bed or sofa and enjoy!
Customization Ideas
- Experiment with different color palettes: try blues and grays for cool tones, or creams and greens for a calm, botanical feel.
- Use bulkier or lighter yarn for a larger throw or lighter coverlet.
- Reverse color placement in squares for a checkerboard effect.
- Make fewer squares for a lap blanket, baby blanket, or even placemats/coasters using the motif.
- Add a more elaborate border if desired, such as a picot or shell stitch edge, for a decorative finish.
Troubleshooting
- Curling Squares: Ensure your tension is even. Add an extra chain in corners if edges curl inward. Block squares before joining.
- Uneven Edges: Double-check stitch counts at the end of each round. Use a stitch marker for the first stitch in every new round. Consistent counting prevents wonky edges.
- Piece Too Large or Too Small: Measure the first square and check against the gauge. Adjust hook size up or down as needed for a perfect fit before making all squares.
- Loose Color Changes: Always fasten off and weave in new color at the start of a round for crisp sections. Carry unused yarn loosely along the back but avoid pulling too tight, which can distort stitches.
- Uneven Tension: Practice with a swatch to get comfortable before starting the main squares. Relax your grip and keep yarn tension even.
Care Instructions
Hand wash gently or machine wash on a delicate cycle with cold water to preserve color and shape. Use mild detergent only. Lay flat to dry on a clean towel or blocking mat to prevent stretching. Avoid bleach or harsh chemicals. If desired, steam lightly with an iron on low while blocking for the crispest stitch definition.
Final Notes
Take time to check stitch counts and tension on each square, blocking as needed for precision. Use the image as a visual reference for color layout and square arrangement. Enjoy the creative process, and don’t hesitate to personalize colors or border style for a blanket that’s uniquely yours and beautifully handmade.
