When summer gets here we make the most of our good weather. In Washington State summers are extended by protecting our patios from breezes and misty mornings.
You can enclose a patio with sunscreen shades and use it year round for BBQ’s and garden sneaks when the sun pops out.
Here is an awesome treatment.
Exterior Shade

Exterior shades seem like they would be perfect for patios. There were a few times last summer when I wanted some shade while having lunch on my patio. The guy in the picture looks like he’s pretty relaxed from all of the shade those blinds are giving him, so I might want to have this for my home. Thanks for posting this!
