Summer shade. Could probably find the wire and curtains at Ikea. Attach one side to the house and the other side to poles, slide the curtains across for shade and slide them back and secure during a storm.
POLYMERIC SAND.... Seals cracks Dry sand tends to get washed away or swept out of paver brick. One solution is to use special polymeric sand that binds together when wetted. Buy premixed bags of sand. A bag ($24) covers about 120 sq. ft. on paver bricks. Make sure there is no sand on the surface of the brick or stone before you wet it. http://www.familyhandyman.com/landscaping/landscaping-tips-for-your-backyard
