I've read on dozens of threads that if 'and' is followed by a dependent clause, no comma should be placed before it, and if 'and' is followed by an independent clause, it should most definitely be proceeded by a comma.
But I've also read that if the information at the end of a sentence is a nonrestrictive modifying clause, it takes a comma. So what about in sentences like this--
And that’s where I found myself some time ago, mental chains binding me to my sea of pillows and blankets that were definitely overdue for a wash.
"blankets that were definitely overdue for a wash" obviously has no verb or subject to stand on its own, so there should be no comma before it, right?
But then, on the other hand, if I don't put a comma before 'and', how do I show that the "...and blankets..." is extra info and only the blankets need to be washed, not the pillows.
