Introduction
This project brings the charm of modern geometric style to your home with a bold, contemporary crochet blanket and matching pillow set. The blanket and pillow cover are crafted from rich purple yarn, featuring a distinctive openwork grid pattern that creates a windowpane or lattice effect across the entire surface. This gives the finished pieces a clean, airy look, with firm texture anchored by spacious square openings.
This blanket and companion pillowcase are perfect as striking bedroom accent pieces or as cozy throws to add style to your living space. The open spaces make the set light enough for year-round use, and the bold pattern stands out in both minimalist and vibrant décor schemes. Not only is this project visually impressive, but it is also highly enjoyable to make—each repeat is satisfying and easy to memorize, making it a meditative pattern for relaxing evenings or productive weekends. Plus, the modular motif-like construction means you can easily customize the size or adapt the pattern for various projects.
This pattern is ideal for anyone looking to cultivate new skills with openwork crochet while creating a polished, functional home accessory that always earns compliments.
Project Overview
The windowpane crochet blanket and pillow are made by working large rectangular panels in rows. The grid effect is created using double crochet stitches with evenly spaced chain spaces that form square windows. Each row alternates between blocks of double crochet and chain-spaces, gradually building the open lattice effect. The entire blanket is made as one piece—no motifs or appliqués—while the pillow cover can be crocheted in two flat panels and joined, or worked as a single long panel folded and seamed.
This construction method means you can easily adjust the size by adding or subtracting repeats and rows, and the clean lines make joining sections seamless if you wish to make extra-large blankets.
Skill Level
This pattern is suitable for advanced beginners and up. You will use basic stitches—chain and double crochet—with some attention to counting stitches and keeping even tension. Once you grasp the pattern repeat, it grows quickly and is enjoyable even for intermediate crocheters.
Materials
- Yarn: Worsted weight (category #4) cotton or cotton-blend yarn will achieve crisp stitch definition and moderate drape. Approximate quantities for a 72×84 inch (183×213 cm) blanket: 2,200–2,400 yards (2,010–2,195 m) in purple (main color). Each 18×18 inch (45×45 cm) pillow cover requires around 350–400 yards (320–365 m).
- Crochet hook: US size H/8 (5.0 mm)
- Tapestry needle: For weaving in ends and seaming
- Scissors
- Stitch markers: Optional, to mark window positions or row beginnings
- Measuring tape
- Buttons or zipper (optional, for pillow closure)
Finished Size
The finished blanket measures approximately 72 x 84 inches (183 x 213 cm), which covers a queen-sized bed with generous drape. Each pillow cover is 18 x 18 inches (45 x 45 cm) to fit a standard throw pillow insert. To adjust sizes, increase or decrease the number of pattern repeats across for width or rows for length. The grid motif is based on a multiple of 6 plus 2 stitches for the foundation row.
Gauge
A 4 x 4 inch (10 x 10 cm) swatch should contain about 2 pattern repeats across by 5 rows in double crochet grid (each repeat includes 3 dc and a ch-3 space). Gauge is not absolutely critical, but adjusting hook size or tension will affect the overall blanket and pillow size.
Stitches and Abbreviations
- ch: chain
- dc: double crochet
- sl st: slip stitch
- st(s): stitch(es)
- sp: space
- sk: skip
Pattern Notes
- Ch-3 at the beginning of each row counts as the first dc, unless otherwise specified.
- The grid is worked in rows, turning your work at the end of every row.
- Each “window” is formed by chaining 3 and skipping 3 stitches from the row below, then working 3 double crochets in the following 3 stitches.
- You may use a stitch marker at the beginning of rows or to mark chain spaces for ease, especially in large blankets.
- When adding new yarn (to join a new skein or change color), do so at the edge of the work and weave in ends neatly for a polished finish.
- Keep tension consistent, especially over the chain spaces, to avoid sagging or puckering squares.
Crochet Pattern Instructions
Blanket: Foundation and Main Body
Foundation Row: Decide on the width of your blanket. For the standard example, chain a multiple of 6 plus 2 stitches (for a queen-size, use about 164 + 2 = 166 chains).
Row 1: Dc in the 4th ch from hook (counts as first dc here and throughout), dc in the next 2 ch, (ch 3, sk 3 ch, dc in next 3 ch) repeat across to last 4 ch, ch 3, sk 3, dc in last ch. Turn. (You should have alternating 3-dc blocks and ch-3 “windows” across the row.)
Row 2: Ch 3 (counts as dc), dc in next 2 dc, (ch 3, sk ch-3 sp, dc in next 3 dc) repeat across to last window, ch 3, sk final ch-3 sp, dc in top of turning ch. Turn.
Row 3 and Beyond: Repeat Row 2 until your blanket measures your desired length (for queen size, about 170–180 rows). Each row should maintain the windowpane look, with chain-3 spaces directly above those in the previous row, and double crochet clusters stacking atop each other.
If adjusting width/length, ensure your foundation is a multiple of 6 plus 2, and work additional or fewer rows for desired length.
Final Row: To finish the top edge, work a final row placing 1 dc in each dc and 3 dc into each ch-3 sp across for a smooth finish. Fasten off and weave in ends.
Pillow Cover
Front and Back Panels (make 2):
Chain 44 (or desired width for an 18-inch pillow, must be a multiple of 6 plus 2).
Row 1: Dc in 4th ch from hook, dc in next 2 ch, (ch 3, sk 3 ch, dc in next 3 ch) repeat across to last 4 ch, ch 3, sk 3, dc in last ch. Turn.
Row 2: Ch 3, dc in next 2 dc, (ch 3, sk ch-3 sp, dc in next 3 dc) repeat, ch 3, dc in top of turning ch, turn.
Rows 3–24: Repeat Row 2 for about 24 rows or until the panel is square. Fasten off, weave in ends.
Assembly for Pillow: Place front and back panels with right sides together. Using whip stitch or single crochet, seam three sides, insert pillow form, and seam final edge. Alternatively, add buttons or zipper closure on one edge for easy removal.
Optional Border (for Blanket and Pillow)
Round 1: Join yarn to any corner. Ch 1, sc evenly around all four sides—work 3 sc into each corner—for a neat frame and to stabilize edges. Sl st to first sc, fasten off and weave in ends.
Assembly and Finishing
Once you have completed crocheting the blanket and pillow panels, carefully block the finished pieces to enhance the crisp, geometric look. Blocking is especially important for openwork designs—gently shape and pin your work to measurements, then mist with water and allow to dry. For the pillow, if using a button or zipper closure, sew it securely along one side before inserting the pillow form. Seam pillow panels carefully, matching each window and solid section to maintain the grid pattern around all edges. Weave in all ends using a tapestry needle, and trim any loose fibers for a polished result. For the blanket, pay attention to the long edges and corners, smoothing out any tension inconsistencies. If desired, crochet a simple single crochet border around the blanket for a more finished appearance.
Customization Ideas
This modern windowpane set is highly customizable to match any living space or taste. Create a dramatic effect by using a neutral base (such as cream or gray) or opt for a two-tone look by using contrasting colors for the solid stitches and chain spaces. For extra coziness, try a bulky-weight yarn or alternate between thinner yarns for a textured effect. You could even incorporate multi-color stripes or gradient yarns for an ombre look. Adjust the pattern size for baby blankets, sofa throws, or even table runners and placemats. Experiment with different yarn fibers—cotton for summer, wool for warmth, or a blend for softness and easy care.
Troubleshooting
- Curling Edges: If your blanket or pillow edges begin to curl, your tension may be too tight on the foundation chain or chain spaces. Gently block your work or use a larger hook for the starting chain.
- Uneven Windows: If the grid squares look distorted, focus on maintaining consistent stitch height and chain length and block your work to set the shape.
- Too Large or Small: Check your gauge before starting the main body. Adjust hook size if needed and ensure you have the correct multiple of stitches for your desired dimensions.
- Loose Color Changes: If changing yarn, always do so at the edge and weave in ends firmly. Avoid knots in openwork sections.
- Uneven Tension: Keep the yarn relaxed when working over chain spaces, and do not pull double crochet stitches too tightly. Take regular breaks and check your stitch consistency often.
Care Instructions
Machine wash finished blanket and pillow cover on a gentle cycle in cold water with mild detergent, if your yarn is machine washable. Lay flat to dry to retain the windowpane shape and avoid stretching. For stubborn wrinkles, lightly steam block or reshape when damp. Always check yarn label instructions for specific care recommendations.
Final Notes
Check your stitch counts regularly to maintain the clean windowpane grid, and adjust tension as needed. Enjoy every step of this truly striking lightweight project, and use the finished image as your visual guide for neatness and motif spacing. Express your creativity with colors and feel proud to display your modern openwork crochet masterpiece!
