VERY helpful!! Thanks!

I have a giant Project for the summer wk where i have to start Upholstering an ottoman with storage and a banana couch. I've started getting the buttons of the furniture but i'm still not sure how to get this upholstered. And we don't have a place to get it done nearby... Is there anyone who could give any tips or link, that would be helpful! Thank you!

Organic fabric will not be stain resistant and someone who buys an organic chair or couch will NOT put stain guard on it... boy was she wrong. She said “OF COURSE!” wow
