Creating a crochet bag with a stunning diamond pattern involves a few key steps: selecting the right yarn, choosing a diamond stitch pattern, and shaping the bag. Here’s a step-by-step guide to help you make one, even if you’re an intermediate beginner.

🧶 Materials Needed
- Worsted weight or cotton yarn (for structure)
- Crochet hook (usually size H/5.0mm or as per yarn)
- Stitch markers
- Scissors, tapestry needle
- Optional: lining fabric, zipper or magnetic snap
💠 Diamond Pattern Options
Diamond patterns in crochet are often achieved through:
- Overlay Mosaic Crochet
- Tapestry Crochet
- Front Post/Back Post stitches (to create a raised texture)
Let’s use a textured front post diamond pattern, which is beginner-friendly and looks elegant.
🧵 Basic Diamond Stitch (Textured) – Swatch Instructions
To understand the pattern first, try a small swatch:
1. Foundation Chain
Chain a multiple of 8 + 3 (e.g., 27).
2. Row 1 (Right Side)
DC in 4th chain from hook and in each across.
3. Row 2
Ch 2 (counts as hdc), turn. HDC in each stitch across.
4. Row 3 (Start Diamond Texture)
Ch 2, FPDC (front post dc) around next DC, DC in next 3, FPDC around next DC, DC in next 3. Repeat.
5. Row 4
Repeat Row 2 (all HDC).
6. Row 5
Shift FPDC one stitch to the left to form a slant: DC in 1, FPDC, DC in 3, FPDC, DC in 1, repeat.
Repeat these rows, widening and then narrowing the placement of the FPDCs to form diamond shapes.
👜 Bag Construction
1. Base
- Make a rectangle with single crochet (SC) rows.
- Size example: 30 stitches x 12 rows (approx. 9″ x 4″).

2. Body
- Turn your base rectangle and begin working in the round around it.
- Start the diamond stitch pattern on the front/back panels; keep the sides in simple DC or SC.
- Repeat the diamond pattern upward to your desired height.

3. Handles
- Crochet straps separately (e.g., with SC in rows until desired length).
- Or create handles by chaining directly into the top edge of the bag, leaving gaps.

4. Finishing Touches
- Sew a lining if desired.
- Add a magnetic clasp or zipper.
- Block the bag lightly for clean lines.

📌 Tips
- Use a stiffer yarn (like mercerized cotton or cotton-blend) for structure.
- Lining the bag helps hold its shape.
- You can incorporate colorwork diamonds using tapestry crochet if you want more contrast.
