Guðbjörg Pálmadóttir’s Bylgja from Ístex’s Lopi 31 is a long pullover knitted from the top down in one colour of Léttlopi, light ash, with ¾-length sleeves. There is no ribbing: the neck is two knit rounds, and the hem and cuffs end with a single purl round. Down the front run four wavy lines — ash heather, dark grey heather, black heather and dark wine — crocheted onto the finished sweater with slip stitches, or sewn in duplicate stitch. Sizes XS to XL. Dark wine (9417) is no longer made; the other four colours still are. Lopi 29 has a different pattern with the same name.

Gauge
15 sts × 24 rows = 10 cm (4″) in stocking stitch on 5.5 mm needles.
Needles
5.5 mm (US 9) circular needles, 40 and 60 cm — the yoke, the body and the sleeves
4.5 mm (US 7) circular needles, 40 and 60 cm — the neck edge and the purl round at the hem
4.5 mm and 5.5 mm double-pointed needles (in the pattern’s list) for the sleeves, 42 to 53 stitches round
3.5 mm (US E-4) crochet hook — for the waves
You will also need
Stitch holders for the sleeve stitches, a stitch marker and a tapestry needle — the pattern’s list leaves them out — and, as the pattern suggests, a finer yarn or thread to draw the waves before you crochet them.
How it is knitted
Knitted in the round from the top down. The neck is cast on with 80 (85, 90, 95, 100) stitches on the 4.5 mm circular and knitted for 2 rounds; on 5.5 mm the yoke is increased in six rounds, four plain rounds apart — one stitch after every 5, then 6, 7, 8, 9 and 10 stitches — to 176 (187, 198, 209, 220), and knitted until it measures 20 (22, 23, 24, 24) cm. The sleeve stitches go on holders and 9 (10, 10, 11, 12) stitches are cast on at each underarm; the body, 128 (137, 143, 153, 162) stitches, is knitted straight until it measures 50 (52, 54, 56, 58) cm and finished with one purl round on 4.5 mm and a loose bind-off. For each sleeve the held stitches go onto the shorter 5.5 mm circular and the underarm stitches are picked up, 42 (45, 47, 50, 53), knitted straight to 38 (40, 42, 42, 44) cm and finished the same way. Last, the waves are crocheted onto the left front with the 3.5 mm hook: the yarn is held inside the sweater and drawn up through the fabric and through the loop on the hook, a line of slip stitches on the surface — or the lines are sewn in duplicate stitch.
Design: Guðbjörg Pálmadóttir — pattern from Lopi No. 31 (no. 23), Ístex.
