Abbreviations
V = turn
CAD = chain stitch (loop)
PA = double crochet (yarn over, pull the needle through, yarn over, bring the needle through, yarn over, pull 2 loops off the needle, yarn over, pull 2 loops off)
PR = slip stitch (stitch the needle, take up yarn, bring the needle back, pull out the loop)
PB = single crochet (stitch the needle, yarn over, bring the needle back, yarn over, pull out 2 loops)
PM = half double crochet (we take yarn, we put the hook in, we take yarn, we bring the hook in, we take yarn, we take 3 loops)
BL = back loop (we make the stitch by inserting the needle only through the back loop of the stitch instead of picking up both loops)
CJ = closed together (two or more stitches closed together. For example 2 DC CJ: yarn over, pick up the hook, yarn over, bring the hook through, yarn over, take 2 loops off the hook and, without taking the other 2 loops off, begin the second double crochet, yarn over, pick up the hook, yarn over, bring the hook through, yarn over, take 2 loops off the hook, yarn over, take all the loops off. A single stitch is created where there were previously two). This creates a DECREASE.
TJ = knit together (two or more stitches knitted by inserting the needle into the same stitch). This creates an INCREASE.
Tips
- In the single crochet rows we make 1 chain stitch in height before the first stitch.
- Half-stitch rows begin with 2 CH in height before the first stitch.
- In the double crochet rows, you start with 2 chain stitches in height before the first stitch.
- The sweater is knitted in the round, closing each round with a PR to the first stitch.

We have already finished the first round.
To knit the other sleeve, we hook a yarn over where we finished Row 11, but on the other side. We repeat the steps from Rows 12 to 29 to knit this sleeve.
C) BODY
We hook a yarn in one of the armholes, where we finished Rnd 11. We are going to knit the body of the sweater downwards in the round, knitting the 38 stitches on each side, which gives us rows of 76 stitches.
On the first row of the body (which would be Row 12 if we continue from the beginning of the neck down), to cover the gap between the armholes when moving from one side to the other, we'll also work in the stitches where we made the sl sts to join the sides in Row 11. We'll call these stitches "Joining Stitches." On the first row, we'll find 4 joining stitches.
R12 - Work 2 SC (the first joining stitch and the next one), 36 SC, 2 SC (the stitch before the joining stitch and the second joining stitch), again 2 SC (the third joining stitch and the next one), 36 SC, 2 SC (the stitch before the last joining stitch and the last joining stitch). There are 38 stitches left on each side, for a total of 76 stitches on the row.
V13 to 22 - 76 PA
V23 - 76 PM
V24 to 25- 76 PB BL
