by That sounds like a fun, eye-catching project! Creating a colorful diamond pattern in a square motif often utilizes the Tapestry Crochet technique or the Corner-to-Corner (C2C) method.
Since the C2C method makes color changes easy and naturally forms diamonds/diagonal lines, I will provide a detailed tutorial for a C2C Colorful Diamond Square.
💎 Colorful Diamond C2C Square Motif
This pattern uses the Corner-to-Corner technique to create a grid of blocks, allowing you to easily ‘paint’ the diamond shape with color changes. This square is built diagonally from one corner to the opposite.
Materials You’ll Need
- Yarn: Medium-weight yarn (worsted/size 4) in at least three colors.
- Color A (Background): Dominant color.
- Color B (Diamond 1): First accent color.
- Color C (Diamond 2): Second accent color (optional, for a multi-colored diamond).
- Crochet Hook: The size appropriate for your yarn (e.g., 5.0 mm).
- Bobbins (Optional but Recommended): Small amounts of yarn for the center diamond are easiest to manage on bobbins to avoid tangling.
- Scissors, Tapestry Needle.
Key Crochet Terms
| Abbreviation | Stitch Name |
| ch | Chain |
| sl st | Slip Stitch |
| dc | Double Crochet |
| Block | (ch 3, 3 dc) or (sl st, ch 3, 3 dc) |
| Inc | Increase |
| Dec | Decrease |
Special Technique: Color Change
To change colors mid-row, work the last stitch of the current color up until the final yarn over. Drop the old color, pick up the new color, and pull through the remaining loops on the hook.
Step-by-Step Instructions
We will create a small 7-Block x 7-Block square.
Part 1: Increasing Rows (R1–R7)
The work increases by one block per row until the desired width is reached (7 blocks).
| Row | Count | Action |
| R1 | 1 Block | With Color A: Ch 6. Dc in the 4th ch from hook, dc in the next 2 chs. (1 Block). |
| R2 | 2 Blocks | Ch 6. Dc in the 4th ch from hook, dc in next 2 chs (Block 1). Sl st into the ch-3 sp of Block 1. Ch 3, 3 dc into the ch-3 sp (Block 2). |
| R3 | 3 Blocks | Ch 6. Dc in the 4th ch from hook, dc in next 2 chs (Block 1). Sl st, ch 3, 3 dc into each ch-3 sp across. |
| R4 | 4 Blocks | Continue the Inc pattern. |
| R5 | 5 Blocks | Continue the Inc pattern. Start Color B: Block 3 should be B. (A2, B1, A2). |
| R6 | 6 Blocks | Diamond Shape: Blocks 3 & 4 should be B. (A2, B2, A2). |
| R7 | 7 Blocks | Widest Point: Blocks 3, 4, & 5 should be B. (A2, B3, A2). |
(Note: Carry the yarn colors loosely along the top of the blocks, or drop and pick them up on the next row).
Part 2: Decreasing Rows (R8–R13)
When the desired width (7 blocks) is reached, we begin decreasing to form the corner.
| Row | Count | Action |
| R8 | 6 Blocks | Dec: Sl st into the first 3 dc of the last block made. Ch 3, 3 dc into the ch-3 sp. Work across. Diamond Shape: Blocks 3 & 4 should be B. (A2, B2, A2). Sl st into the last ch-3 sp. Do NOT ch 6. Turn. |
| R9 | 5 Blocks | Dec: Sl st over the first block. Diamond Shape: Blocks 3 should be B. (A2, B1, A2). |
| R10 | 4 Blocks | Dec: Sl st over the first block. Diamond Shape: All blocks should be A. (A4). |
| R11 | 3 Blocks | Dec: Sl st over the first block. (A3). |
| R12 | 2 Blocks | Dec: Sl st over the first block. (A2). |
| R13 | 1 Block | Dec: Sl st over the first block. (A1). Fasten off. |
Detailed Color Pattern (R5 to R9)
If R is the row number and the number indicates the block count in that row:
| Row | Color Pattern (A = Background, B = Diamond) |
| R5 (5 blocks) | A, A, B, A, A |
| R6 (6 blocks) | A, A, B, B, A, A |
| R7 (7 blocks) | A, A, B, B, B, A, A |
| R8 (6 blocks, Dec) | A, A, B, B, A, A |
| R9 (5 blocks, Dec) | A, A, B, A, A |
Finishing
- Weave in Ends: C2C leaves many ends. Use your tapestry needle to securely weave them into the back of the corresponding colored blocks.
- Blocking: C2C squares benefit greatly from blocking to ensure they are perfectly square and flat, ready for joining.
You now have a vibrant, diamond-patterned square! What project will you be making with these motifs?
