A crisp cotton yarn with a nautical-inspired, navy and white, chevron insert makes a light summer tank that would work great over a stretchy tank top or under a blazer for an evening out. The button-up side means you can get in and out of it without stretching it out, which makes it the perfect top for any summer outing.

Pattern Notes

There are “at the same time” instructions for the Front, please read through the pattern before beginning.
Ch-3 counts as 1 dc.
It will be easiest from an ends-weaving-in standpoint to work the Front with two skeins of A Row 2 – one on either side of the chevron pattern. You can then float the unused colors up the side of the chevron, on the wrong side.
The fact that there are not the same number of chains for the Front as for the Back is not a typo – the chevron pattern affects the chains on the Front!

Pattern

Front

With A, ch 76 (82, 88, 94, 100).
Row 1: Dc in 4th ch from hook and in each ch across. Ch 3, turn. (74 (80, 86, 92, 98) dc)
Row 2 (RS): Dc in each dc across until 26 (29, 32, 35, 38) dc have been completed, FPtr in each of next 2 dc, sk 2 dc, dc in next dc , (ch 1, sk 1 dc, dc in next dc) twice, ch 1, 2 dc in next dc, ch 2, 2 dc in next dc, (ch 1, skip 1 dc, dc in next dc) 3 times, sl 2 dc, FPtr in each of next 2 dc, dc in each dc to end. Ch 3, turn.
Row 3: Dc in each dc across to FPtr, change to B, BPtr in each of next 2 FPtr, sk next dc and ch-1 sp, dc in next dc, (ch 1, dc in next dc) twice, ch 1, (2 dc, ch 2, 2 dc) in next ch-2 sp, ch 1, sk 1 dc, dc in next dc, (ch 1, dc in next dc) twice, sk next ch-1 sp and dc, BPtr in each of next 2 FPtr, change to A, dc in each dc to end. Ch 3, turn.
Row 4: Dc in each dc across to BPtr, change to B, FPtr in each of next 2 BPtr, sk next dc and ch-1 sp, dc in next dc, (ch 1, dc in next dc) twice, ch 1, (2 dc, ch 2, 2 dc) in next ch-2 sp, ch 1, sk 1 dc, dc in next dc, (ch 1, dc in next dc) twice, sk next ch-1 sp and dc, FPtr in each of next 2 BPtr, change to A, dc in each dc to end. Ch 3, turn.
Rows 5-6: Rep Rows 3-4 but do not change color.
Rep Rows 3-6 for pattern until work measures 13 (13, 14.75, 14.75, 16.5)” or desired length, ch 1, turn at the end of the last pattern row, WHILE AT THE SAME TIME following increase instructions below.

Increase Section

When work measures 5 (5, 6, 6, 7)” from start increase by working 2 dc at the beginning and end of the next row, and every 3rd row following, until 6 sts have been increased (3 increase rows worked).
Final Row: Sc in each st and ch-sp across. End off.

Back

With A, ch 70 (76, 82, 88, 94).
Row 1: Dc in 4th ch from hook and in each ch across. Ch 3, turn. (68 (74, 80, 86, 92) dc)
Work even in dc until work measures 5 (5, 6, 6, 7)” from start, rep Increase Section from Front.
Continue to work even until work measures same as Front, ch 1, turn at end of last dc row, and rep instructions for Final Row of Front. End off.

Straps (Make Two)

With A, ch 5, join into a ring with sl st in first ch.
Rnd 1: Ch 3 (counts as 1 dc), dc in each of next 4 ch, join rnd with sl st in top of beg-ch.
Rnd 2: Ch 3, dc in each of next 4 dc, join rnd with sl st in top of beg-ch.
Rep Rnd 2 for pattern until straps measure 15 (15, 16, 16, 17)” or desired length. End off.

Finishing

Sew Front to Back along right-hand side seam.

Edging and Button Band

With RS facing, join A with sl st in top left-hand st of Back.
Row 1: Work evenly in sc across left-hand Back edge, work 3 sc in corner, sc in opposite side of foundation ch along entire bottom edge, adding 1 sc at seam if needed so it lays flat, 3 sc in corner, work evenly in sc across left-hand Front edge, ch 1, turn.
Row 2: Sc in each sc across to first st in corner, ch 1, turn.
Rows 3-4: Sc in each sc across, ch1, turn after Row 3, end off after Row 4.
Weave in all ends.
Sew buttons to button band, evenly spaced. The space between the first 2 dc in each row of Back, reinforced with the sc edging, act as buttonholes so you can easily change the number/spacing of buttons.
