My son & I built a deer blind. I painted the blind green with brown trim. It looks good but I want to camouflage the blind. I bought brown, black & grey spray paint for the job. Any thoughts on how to make a nice pattern. I googled but nothing .Thanks7L. I need to finish this tomorrow. So, I won't have time to get a stencil. I'll be free handing. Yikes I want it to look good. Help please!!!
