I always rewrite patterns like this before I start. Like this:
Ch 4, join with slip st to form ring.
4 dc in ring,
(ch3 ,5dc in ring) 3 times, This I sometimes write out three times instead: ch3 ,5dc in ring, ch3 ,5dc in ring, ch3 ,5dc in ring
join with slip st to top of beg ch-3.
Rnd 2 Ch 2,
(yo, insert hook in next dc, yo and pull up a loop, yo and pull through 2 loops) 4 times,
yo and pull through all 5 loops on hook (dec made)
this is a decrease. 4 stitches together and it seems to be 4 dc together as far as I can see. Just follow through and you'll
