Fabric in colors and patterns of your choice
There are two great tutorials that I found for this project. One from Danielle Thompson and one from Boho Weddings. Both are great and its worth taking a look at both so you can see a variety of pictures to really see how to do it. Seriously, pictures ARE worth a thousand words. Most of the time I don't even need to read the directions if the pictures in a tutorial are good enough. I've included my own pictures for you also, although mine are much inferior to the others.
Have a great weekend everyone!
