Yeah... thank you for the tip with the sleeves, I absolutely want to shorten them (bold lie - in reality I am dreaming of making a sweater or cardigan with puff sleeves with the help of this book)
And with the neckline... this can change so much. I once made a simple sweater were I followed the pattern word for word and the neckline looked so strange, much to wide and it had no stylistic connection to the rest of the sweater... I hope you find a solution.
