What you will need:
-a hot glue gun
-salt (for snow!)
-mason jars (can be found at the grocery store)
-miniature bottle brush Christmas trees (can be found at any craft store)
Step 1: Unscrew the mason jar lid and hot glue the tree to the inside.
Step 2: Fill the mason jar with some "snow." I used salt, but you could get creative here!
Step 3: Screw the lid back on. Annnd done. I love easy projects like this.
