Detailed tapestry-crochet pattern to make a 50" x 60" (127 x 152 cm) argyle blanket with a central Plymouth-style logo inset. Worked in single crochet (tapestry crochet) so colorwork sits flat. This pattern uses a diamond-repeat argyle grid and a 21x21 pixel logo chart you place in the center diamond. Read all notes before starting.
Approx 50" x 60" (127 x 152 cm). Size will vary with gauge; see notes for adjustments.
Provide conversions for common hooks/needles. Use US terms in pattern.
Note: "UK old" sizing here is the traditional numeric UK hook size. If you prefer metric only, use the mm value.
16 sc x 18 rows = 4" / 10 cm using US I-9 (5.5 mm) hook in single crochet (tapestry style). Always make a swatch in single crochet with two colors to check your tension because tapestry depends on even tension and carried floats.
The argyle pattern is created from diamond motifs. Each diamond motif is 20 sts wide x 28 rows tall. The sample throw below is 5 diamonds across and 7 diamonds tall; total working stitches per row = (diamond_width * diamonds_across) + 1 selvedge = (20 * 5) + 1 = 101 ch (plus 1 turning ch).
To adapt size: change number of diamonds across or up; foundation chain = (diamond_width * diamonds_across) + 1.
With Color A (Background): ch 102 (101 sts + 1 turning ch) to make 5 diamonds across. Adjust chain if you want more or fewer diamonds across.
Each diamond block is 20 sts wide x 28 rows high. The stitch-by-stitch color map for one full diamond is written below as an abbreviated row set. You will repeat these rows across the row with color shifts for the staggered diamonds. For speed, work entire row across blanket following chart for each row.
Row 1: (RS) 20 sts Color A (background) Row 2: 20 A Row 3: 3 A, 14 B, 3 A Row 4: 2 A, 16 B, 2 A Row 5: 1 A, 18 B, 1 A Row 6: 20 B Row 7: 20 B Row 8: 1 A, 18 B, 1 A Row 9: 2 A, 16 B, 2 A Row10: 3 A, 14 B, 3 A Row11: 4 A, 12 B, 4 A Row12: 5 A, 10 B, 5 A Row13: 6 A, 8 B, 6 A Row14: 7 A, 6 B, 7 A Row15: 8 A, 4 B, 8 A Row16: 9 A, 2 B, 9 A Row17: 11 A, 9 A (solid background) — begin mirror to complete diamond ...continue symmetrical up to Row28 to complete diamond.
Note: The diamond is symmetric vertically; chart above gives central shaping. When placing diamonds next to each other the edge columns of adjacent diamonds will touch; use correct color for that stitch according to the full row chart across the blanket.
Work each row across the entire foundation chain following a full-row color chart. Because diamonds are staggered, the color for each stitch comes from its diamond. Create a full-row tracking chart before beginning: create graph paper or spreadsheet that maps each of the 101 stitches across and 196 rows (28 rows x 7 diamonds tall) — this helps you track color for every stitch.
The logo is a 21x21 pixel chart designed to sit centered inside the central diamond (replace part of the diamond color with logo pixels). Use Color E for logo foreground and Color B or A as background depending on desired contrast. Work the logo rows as part of your regular tapestry rows in the central diamond area — carry colors across or stop/start and sew in with duplicate stitch if you prefer sharper edges.
Legend: X = Logo color (Color E), . = non-logo (use the diamond color in that pixel) 21x21 logo (row 1 at top): ..................... ..................... .......XXXXX......... ......X.....X........ .....X.......X....... .....X.......X....... ....X.........X...... ....X.........X...... ....X....X....X...... ....X....X....X...... ....X.....X...X...... .....X.......X....... ......X.....X........ .......XXXXX......... ..................... ..................... ..................... ..................... ..................... ..................... .....................
Place this 21x21 block centered horizontally and vertically within the central diamond. Because the diamond is ~20x28, you may need to shift logo up 3 rows or reduce one column of diamond color — use your swatch to confirm placement. If you prefer exact pixel-perfect placement, work the logo using duplicate stitch after the blanket is finished.
To make the blanket larger or smaller, change the number of diamonds across (affects foundation chain) and number of diamonds tall (affects total rows). Each diamond unit is 20 sts wide x 28 rows high in this pattern. Multiply those numbers for your target dimensions using your gauge.
This pattern provides a graph and instructions for a generic argyle-style blanket and a 21x21 pixel logo chart for personal use. If you are recreating a trademarked logo, ensure you have permission for commercial use and follow local copyright/trademark rules. For charity or personal gifts this is typically acceptable; selling items with a trademarked logo may require permission from the trademark holder.
If you want a printable full-row chart: export your diamond grid and logo into graph paper (21 pixels per logo row) or use free charting software to create a color-by-stitch chart. Label each row left-to-right for RS rows and right-to-left for WS rows to avoid mistakes.
