The image below shows the backside "support" for the couch backrest.
Pictured above is the final version of the couch draped with fresh sod. The kids don't look particularly impressed in this photo. Let's hope the grass couch holds together a little longer and that I can capture all the fun that a grass couch adds to ones life.
Thank you to my local liquor store for helping to make this project happen in more ways than one.
