Sometimes you need to let the more gelatinous parts stay where they are, with notes all around them. Some pages with a lot of writing and cross outs on them can't actually be rewritten. The new words are just ciphers for "help! help!"
I'm putting those parts aside for now and going forward, trusting that in a month or six, I won't be painting and patching the old sections but instead seeing daylight and knowing where to cut.
