Start hot gluing your yarn 4-5 strands at a time across the bottom of the front of your wood. Hanging your wall decor.
I chose hot glue because it isnt permanent and the wood will come off the wall.
Take 3 strands of yarn the length of your wooden round and hot glue them horizontally over the top of your hanging pieces to clean up the edge. All you need are some round logs a chop saw to cut the logs into small rounds and some hot glue to attach the wood to your wall.
