This is one of my favorite DIY's to date. It was such an easy (cheap!) project and looks super expensive. I used this tutorial from sweet paul make.
Here's the how to:
I started with boiling water, Rit royal blue dye and some burlap I had left over. I cut the burlap down and left the edges rough. Mix up the dye according to the instructions.
Wet and roll up the burlap...
Then dip in the dye as many times as you need to get the color you want. I went for a more ombre look by soaking the ends more than I did the middle. Then rinse out the dye until it runs clear. Repeat on other side. Rinse then let dry and you are done!
