I've seen this done in photos and on my tumblr, so I just took a shot at it. It's not too hard, obviously. I hope to inspire some of you who haven't seen this cute little idea yet. And I also know some people who have scraps of fabric they have yet to use, so here's a solution.
I just got some hemp from walmart ($5) and some fabric from my favorite thrift store. (All about $3.50) Those triangle shapes you see are cut fold at the top with an identical triangle on the other side. It's just a diamond folded in half.After cutting everything out and figuring out my pattern, I hot glued it all together. Easy enough. And I love love love how it looks. I've also seen people do this and hang it right on a wall, which also looks neat.
