Abbreviations
V = turn
CAD = chain (loop)
dc = double crochet (yarn over, insert needle, yarn over, bring needle back, yarn over, pull through 2 loops on the needle, yarn over, pull through 2 loops)
PR = slip stitch (insert needle, yarn over, bring needle through, pull up loop)
PB = single crochet (insert the needle, yarn over, bring the needle back, yarn over, pull through 2 loops)
PM = half double crochet (yarn over, insert hook, yarn over, bring hook back, yarn over, pull through 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, insert hook, yarn over, bring hook to hand, yarn over, pull up 2 loops from the hook and, without pulling up the other 2 loops, begin the second double crochet, yarn over, insert hook, yarn over, bring hook to hand, yarn over, pull up 2 loops from the hook, yarn over, pull up all loops. A single stitch is created where there were previously two). This creates a decrease.
TJ = knitted together (two or more stitches knitted by inserting the needle into the same stitch). This creates an INCREASE.
Tips
- In the single crochet rounds, we make 1 chain stitch before the first stitch.
- The rounds in the middle stitch begin with 2 CHA of height before the first stitch.
- In the double crochet rounds, start with 2 chain stitches before the first stitch.
- The sweater is knitted in the round, closing each round with a slip stitch to the first stitch.

We have already finished the first round.
To knit the other sleeve, attach the yarn to the stitch where you finished row 11, but on the other side. Then repeat the steps from rows 12 to 29 to knit this sleeve.
C) BODY
We attach the yarn to one of the armholes, where we finished row 11. We will knit the body of the sweater downwards in the round, knitting the 38 stitches on each side, which gives us rounds of 76 stitches.
On the first row of the body (which would be row 12 if we continue from the beginning of the neck downwards), to cover the armhole gap when going from one side to the other, we will also knit in the stitches where we made the slip stitches to join the sides in row 11. We will call these stitches "joining stitches". When working the first row, we will find 4 joining stitches.
Round 12 - Knit 2 dc together (the first joining stitch and the next one), 36 dc, 2 dc together (the stitch before the joining stitch and the second joining stitch), again 2 dc together (the third joining stitch and the next one), 36 dc, 2 dc together (the stitch before the last joining stitch and the last joining stitch). We have 38 stitches left on each side, a total of 76 stitches for the round.
