Lost crochet pattern EDITED: I found it!

Hey crafters, I have a question.

I've been working on a blanket for a pretty long time— several months. Not because it's hard or especially time-consuming, but because I have a habit of picking it up and then not working on it for weeks.

Anyway, I've been working on it a lot lately because it's almost done. I went to pick it up yesterday, and I LOST THE PATTERN. I got it for free on the internet, and I've been looking and looking, but I can't find it online anywhere.

Any advice??

EDITED: I found it! My kid threw it behind the couch, and it was stuck between the couch and the wall, which is why I didn't see it when I looked under the couch. Thanks for your suggestions!
