Sorry for the lack of a step-by-step but they were very labor intensive (My husband is complaining about his back hurting after helping tape a panel. Some men just aren't built for crafts!) and I just wanted to get them done so as not to spend my entire weekend working on them when I could be goofing off. Enjoy and feel free to ask any questions and I will do my best to help out since I was a novice with fabric painting before this project.
Below is the view from outside. You can see how the paint is slightly visible (it only bled through a little to the other side). At night it will look really cool because of the light from inside making the chevrons show up more. I like to let the neighbors have something nice to look at as well :)
