altering sewing patterns: general and specific q's
i'm currently working on a hoodie using a hoodie pattern, but i'm hoping to convert the hood into an obnoxiously oversized collar. and for the future, are there any general rules in making/altering sewing patterns?
( i got my pattern from http://thegreenpepper.com/adults.html
#543 the hemmed hoodie. it was the closest to what i wanted)
