Long Lace Vest
450 (550)g of light-blue yarn (55% cotton, 45% polyacryl; 85m/50g);
Crochet hook 6.
Size: S/M (L/XL).
Main pattern: the quantity of sts is multiple 10 + 6 + 1 chain st increase. Work due to the scheme. Start every row with 1 chain st increase or 4 chain sts instead of the 1st treble crochet. Stat with sts before pattern repeat, pattern repeat, finish with sts after pattern repeat. Make 1st-6th rows x once, then, repeat 3rd-6th rows.
Stitches control: 15 sts x 5,5 rows = 10 x 10 cm.
Make 66 (86) chain sts + 1 chain st increase and work with main pattern. In 7 cm = 4 rows from the set-up row, make 1 x 50 (60) chain sts from both sides for front and continue work on all 166 (206) sts and continue work due to the pattern on newly chain sts, make groups of treble crochets and single crochets in the 1st row due to the 1st row of the scheme. For arm-holes, in 40 cm = 22 rows from the set-up row of back or in 33 cm = 18 rows from the set-up row, divide your work into front (= the first and last 50 (60) sts) and back (= central 66 (86) sts) and make 22 cm = 12 rows (29 cm = 16 rows) on all details. Then, for collar, continue work on all 166 (206) sts as one-piece cloth. In 76 cm = 42 rows (83 cm = 46 rows) from the set-up row of back or in 69 cm = 38 rows (76 cm = 42 rows) from the set-up row of front, finish your work.
Fasten your vest with 1 circle row of single crochets and 1 circle row of “crab stitch”.
