Here's the pattern for the sleeves:
1st row: K2, *(p2,k1) twice, k2tog, yfwd, yrn, p1, (k1,p2)twice, k1, repeat from * to last st, k1, cast on 16 sts. You will now have 115 sts on needle.
2nd row: P1,*p1,(k2,p1)twice, p3,(p1,k2)twice,repeat from * to last 2 sts, p2, cast on 16 sts. You will now have 131 sts on needle.
3rd row: K2, *p2,k1,p2,k2tog,yfwd,k1,yfwd,s1,k1,psso,(p2,k1)twi ce,repeat from * to last st, k1
4th row: P1, *(p1,k2) twice, p5, k2 p1,k2, repeat from * to last 2 sts, p2
1st to 4th row resets pattern.
Continue unti 64 pattern rows have been worked from start of sleeves.
SO I knitted Rows 1 thru 4, I'm back to row 1 and noticed that pattern repeats exactly the same (meaning the yarn over didn't shift in order to make the diamond pattern).
If I follow the back pattern like you suggest (salmonmac), do I do the CO on the 5th and 6th row and so forth?
