It's been 35+ for the past four days (hottest February weather for 40 years) but prior to the heat kicking in, I finished the back and front of my cardigan. In the end I unravelled every attempt at eyelet holes and cables, deciding that the simple look was ultimately the best.
I'll knit the sleeves at the same time, which has three advantages. 1/ I won't suffer from second-sleeve syndrome (where one gets so bored with the knitting that the second sleeve is never knitted). 2/ It guarantees they will both be the same length and shape. 3/ If I run out of blue yarn (very likely) I will have a pink segment in the same position on each sleeve.
