I knitted this baby vest with only baby yarn. Even the buttons are made of baby yarn.
How I made :
With knitting needle (size 3) take 76 loops and knit garter stitch for 4 rows.
After 4 rows of garter stitch make bottonholes to pass the cord through. For front band 5 loops, all garter stitch to the end.
For yoke participation; 5 loops front band, 10 loops right front, 1 loop increasing part, 10 loops right arm, 5 loops side band. You knit yoke 35 rows plain knitting. At increasing parts, at every front side you make increasings. When you finish the yoke, knit 3 rows of garter stitch and you make armholes.
The pattern of body part is 10 rows moss stitch, 10 rows plain knitting. After repeating the pattern 3 times, knit 3 rows garter stitch and cast off. Make crochet laces for the edges of arms and collar. Make a cord with a white yarn. Stitch the cord with blue yarn. Adorn as you wish.
