I'm not sure what you're getting at.
How is it easy enough to reduce armhole shaping and get the arms the right size?
The neck shaping corresponds to armhole shaping??? I need a Xanax
Sounds like you're saying to rewrite the patterns. Problem is the whole book is written with a 44" "small".
I need an easier way or the book is worthless to me.
I did figure out that I can drop a needle size on the cabled sweater to get it to 42" which I can deal with. Maybe even throw in an extra cable and get it to go down a little more.
The saddle shoulder ribbed sweater would need to be tighter so I think I'll just do a raglan with that pattern stitch.
While I was messing around figuring those out I did some math to what I would like to do and I don't see why it wouldn't work. Everything seems to follow certain ratios (except the saddle of the saddle shoulder pattern).
I don't have a problem with the pattern stitches. That is pretty simple math of making the chest size fit into the multiple of stitches the pattern stitch requires.
I can even handle doing small measurement tweaks.
My issue is with the shaping ratios to get the pieces to fit together and fit after it's done. The sweaters I've made to this point haven't had any special armhole shaping so I'm in the dark about how to write that to match the arm.
