I'm quite new to knitting - am attempting a ribbed vest!
However I'm not sure how to increase the pattern for my growing baby.
The patterns starts with front 59 (65:71) but have cast on 83.
For the sleeves on the original pattern it requires cast on 3 sts at beg of next 4 rows, 71 (77:83)
shape neck patt 28 (30:32), cast off nxt 15 (17:19). dec one st at neck on next 5 rows 23 (25:27).
What I'm trying to get at, is there some sort of formula to work out the increase in sts? OR is there something obvious that I'm missing?
