The sun is out, and it is time to bust out your picnic baskets and frisbees. But a picnic wouldn't be complete without a blanket! Impress all your fellow picnic-goers with this practical DIY project. One of my complaints about picnics is the wet spot you get on your backside after mistakenly positioning your blanket in a freshly-watered patch of grass. This picnic blanket is both soft flannel and a waterproof vinyl, preventing those bothersome soggy backsides while keeping things soft enough to watch the clouds.
