With the hanging string, this wall hanging is 32" tall and 33" wide. From the dowel to the bottom it is 20". Hang from either a nail or a command hook.
So this knot repeated here is called a berry knot (because it looks like a berry, duh), and it's one of my favorite knots because there is just so much TEXTURE! It takes absolutely forever because it involved tying one knot about seven times then folding the strands over themselves to make the knot stick out, but it's so worth it.
