Boho Diamond Mesh Tank Top

A breezy, lightweight summer tank worked in an airy diamond mesh stitch. The open lacework gives effortless boho drape and keeps you cool, while the simple two-row repeat makes it a relaxing, beginner-friendly project. Worked in two flat panels and seamed — no complicated shaping required.

Skill Level

Easy — repetitive 2-row mesh pattern; basic seaming.

Sizes

Instructions are written for size M, with other sizes in parentheses: XS (S, M, L, XL). Mesh is stretchy; choose the size closest to your bust for a relaxed fit, or size down for a fitted look.

Materials

• Yarn: Sport weight (#2 Fine) 100% cotton, approx.
  • XS: 700 yd (640 m)
  • S: 760 yd (695 m)
  • M: 820 yd (750 m)
  • L: 900 yd (825 m)
  • XL: 980 yd (895 m)
• Hook: US G-6 / 4.0 mm (or size needed for gauge)
• Notions: Tapestry needle, stitch markers, scissors, blocking mat & pins

Gauge

In diamond mesh pattern, blocked and relaxed:

• 5 diamonds = 4 in (10 cm) wide
• 6 mesh rows = 4 in (10 cm) tall

One diamond = one (ch-4, sc) unit. Make a swatch of at least 6 diamonds × 8 rows to confirm. Blocking opens the mesh — always block your swatch.

Abbreviations (US Terms)

• ch — chain
• sc — single crochet
• sp — space
• st(s) — stitch(es)
• sl st — slip stitch
• rep — repeat
• RS / WS — right side / wrong side
• [ ] — repeat instructions within brackets as directed

Special Stitch: Diamond Mesh

The fabric is built from ch-4 loops anchored with sc. Each ch-4 loop forms one side of a diamond; stacked rows create the diamond lattice.

• Foundation mesh: ch 4, sc into designated st; rep.
• Mesh row: ch 4, sc into the next ch-4 sp (center of the loop below); rep.

Placing each sc into the center of the loop below is what forms the crisp diamond shapes.

Pattern Notes

1. Worked flat in two identical panels (Front & Back) from the bottom up. The Front and Back are worked the same until the neckline/strap split, where the Front has a lower scoop.
2. The turning ch-4 at the start of each mesh row counts as the first half of the first loop.
3. Stitch counts are given as number of diamonds (ch-4 loops) at the end of each row.
4. Diamonds per panel: XS 19 (S 20, M 22, L 24, XL 26).
5. Foundation chain = (diamonds × 4) + 1.
   • XS 77 (S 81, M 89, L 97, XL 105) ch.
   • Check (M): 22 × 4 = 88, + 1 = 89 ✓
6. Keep tension even and loose for maximum drape.

Instructions

FRONT PANEL

Foundation Row (WS): Ch 89 (see Note 5 for your size).

• Sc in 6th ch from hook (the skipped 5 ch = first ch-4 loop + turning). Ch 4, skip 3 ch, sc in next ch; rep across to end.
• Diamond count: XS 19 (S 20, M 22, L 24, XL 26).
• Check (M): 89 ch − 1 base sc ch = 88; 88 ÷ 4 = 22 loops ✓

Row 1 (RS): Ch 4 (counts as first loop), turn. Sc in first ch-4 sp. Ch 4, sc in next ch-4 sp; rep across, working final sc into the turning-ch loop of the row below.

• Diamonds: 22 (all sizes as established).

Rows 2–30 (S: 2–30, M: 2–31, L/XL: 2–32): Rep Row 1.

Continue in mesh pattern until panel measures 14 in (35.5 cm) from foundation, ending after a WS row.

• Check (M): 14 in ÷ (4 in / 6 rows) = 21 rows ✓ (foundation + 21 mesh rows).

Neckline & Strap Split (Front)

Divide the diamonds into two shoulders, leaving a center gap for the scoop neck.

Diamond division (M shown; adjust proportionally):

• Right shoulder strap: 6 diamonds
• Center front neck: 10 diamonds (unworked)
• Left shoulder strap: 6 diamonds
• Check (M): 6 + 10 + 6 = 22 ✓

Size strap/neck breakdown:

Right Strap – Next Row (RS): Ch 4, turn. Work in mesh across the first 6 (5, 6, 6, 7) diamonds only. Turn, leaving remaining diamonds unworked.

• Diamonds: 6 (5, 6, 6, 7).

Continue in mesh pattern on these strap diamonds for 9 more rows, or until strap measures 6 in (15 cm). Fasten off.

• Check (M): 6 in × 6 rows/4 in = 9 rows ✓

Left Strap: With RS facing, skip the center 10 (9, 10, 12, 12) diamonds. Rejoin yarn with a sl st into the next ch-4 sp. Ch 4 and work in mesh across the last 6 (5, 6, 6, 7) diamonds.

• Diamonds: 6 (5, 6, 6, 7).
• Work as for Right Strap for the same number of rows. Fasten off.

BACK PANEL

Work exactly as the Front Panel through the body (Foundation through 14 in / 35.5 cm).

Back Neckline & Strap Split: The Back has a higher, shallower neck. Work the body to 16 in (40.5 cm) before splitting (2 extra rows / 3 rows deeper straps).

• Check (M): 2 extra mesh rows = ~1.3 in, giving a higher back neck ✓

Then split identically:

• Each strap: 6 (5, 6, 6, 7) diamonds; center back neck: 10 (9, 10, 12, 12) diamonds.

Work each Back strap in mesh for 6 rows (shorter, since the back body is longer) or until straps match the Front strap length when laid flat. Fasten off.

Tip: Lay Front and Back together and confirm the shoulder points align before seaming — total shoulder-to-hem length should match on both panels.

Finishing

1. Block both panels to the finished measurements, pinning to open the diamond mesh evenly. Let dry completely.

2. Shoulder Seams: With RS together, whipstitch each Front strap to the corresponding Back strap using the tapestry needle. Weave through the ch-4 loops for an invisible join.

3. Side Seams: With RS together, align the side edges. Beginning at the lower hem, whipstitch or sl st the side edges together, leaving the top 7 in (18 cm) open on each side for the armholes.

   • Check: seam from hem up 14 in, leave 7 in armhole = fits the 21 in strap-length silhouette ✓

4. Neckline & Armhole Edging (optional, boho picot): With RS facing, join yarn at any point of a neckline or armhole edge.

   • Round: Sc evenly around, working sc, ch 3, sl st in first ch (picot), sc spaced approximately every 2 sc for a delicate boho picot trim. Sl st to first sc. Fasten off.
   • Keep the edging loose so the neckline and armholes retain their stretch.

5. Hem Edging (optional): Work 1 round of sc around the bottom hem for a clean finish, or leave the mesh open for a lacy scalloped look.

6. Weave in all ends securely, threading through the sc anchors rather than the open loops so they stay hidden.

Care Instructions

Hand wash cool, lay flat to dry, and re-block as needed. Cotton mesh may relax with wear — reshape when damp.

Design Notes for the Maker

• For a cropped boho look, work fewer body rows (stop at 11–12 in before splitting).
• For a longer tunic, add mesh rows in multiples of 2 before the split — every 3 rows adds ~2 in of length.
• Add wooden or shell beads to the picot edging for extra boho flair.

Enjoy your breezy diamond mesh tank!
