Liz, there are a good number if you type "boho wall hanging" in the search box. Here is one I chose for you, but there are many more: https://www.hometalk.com/30201423/diy-boho-wall-hanging
The easiest is to hang a tapestry, quilt, or old rug...the older or more broken in the better! Use natural materials like tree branches or driftwood for hanging rods.
Love this one. Its so soft and beautiful
This shower curtain wall hanging is easy and looks great!
