Revisions and knitting

I'm in the middle of revising my current work-in-progress, Snowbound with the Earl. I have decided that revising a book is a bit like unpicking a home-knitted jumper that didn't quite go right. You have to unpick all those threads you wove together to tweak some, cut some out, or add some new ones in, and I'm at the part in the process where I've pulled the book apart, and I'm looking at a mess of spaghetti, thinking, 'How the heck am I going to put that back together? Where do I start?'

Not sure there is any golden rule. You just start. Knit one, purl one. And hope that the end result will not just have arms and a neck hole, but will be stylish and comfy and so much better that than the old one. Sigh. Wish me luck!
