We purchased several boxes of these last year to cover our concrete patio outside, but didn't get them put down until a few weeks ago. They're beautiful! We just ordered more because we ran out before completing the outer edge. The new ones just arrived and are just like last years, except they are a slightly lighter shade, which won't be a problem because they will be along the edge of the patio. 
Our only concern is how they will hold up after a few years? The info in the box said to "oil" them a couple times a season, but didn't say what kind of oil to use!! Would like to have more info...Love them for now!!
