I don't know what gets into me. Where does my sense of proportion go? I think it was the word 'simple' in the title. A simple little old jacket. Designed in 1934? Nothing but garter stitch. Blow that off in a week. No trouble.
I have a 'to knit' wish list as high as the Eiffel Tower -and I'm slogging away with charity shop yarn, and it's taking ages! I have a lot less time at the moment, but still...
The back and sides are finished, and I cast on for the back yoke - but the pattern gives practically no information, so what if I haven't done it right? You pick up and knit 70 stitches 'across the back.' What does that mean? Up to what point of the armhole shaping should I go?
After three inches of worrying, I realised the sensible thing to do was stop, knit a sleeve and then see how the sleeve would fit into the back shaping. Read the sleeve instructions - they are knitted sideways and the sleeve cap is done with short rows! 'Simple' Oh ha ha. Just carry me away, now!
Cast on for the sleeve and knit an inch. Sleeves take ages whatever direction you knit them in!
