Items you will need: Yarn or Ribbon, A Hot Glue Gun, and Wood Letters (found at any local craft store)
First, use the hot glue gun to glue the wood letters together. For the scrabble letters just glue the whole side. When gluing the other wood letters just put glue where the letters touch.(This is why I used an upside down M instead of a W in the word snow) Do this to all the letters.
Then, add ribbon to the back so you can hang the ornaments onto the tree.
Finally, add any additional decorations to the ornaments and your done, enjoy!
