K2tog. Knit to last 4 (4-5-5-5-4) sts. Cast
off rem 4 (4-5-5-5-4) sts.
Rejoin yarn and purl 1 row.
Dec 1 st at neck edge on next and every
following alt row 3 (3-2-4-4-5) times
more, AT SAME TIME, dec 1 st at raglan
edge (as before) until there are 3 sts.
Above is the pattern. When it says to cast off and later to rejoin, am I cutting the yarn and rejoining it again? Very lost here. Thank you for your help.
