Here is my favorite one of the bunch..
For this one, I just gathered small twigs, trimmed to size with scissors and hot glued the twigs on. To soften the dark brown color of the sticks, I painted a thin layer of cream paint and gently wiped some paint off.
Pretty easy, wouldn't you say?
Here's another letter from the wall..
I just hot glue dried beans onto my letter for an interesting texture.
