Going to use these for two projects with the sun blocking screen material not coolaroo cloth but the finer mesh that they make blinds inside and outside to block heat and sun in several weights. I also removed coolaroo from some outdoor blinds we liked and replaced with the see through screens last year. So now have the coolaroo cloth to do something with. If there's some of these left over I intend to use these to help hang the pieces over a back 20 foot long covered patio to help cut down the heat that afternoon sun builds up there. We noticed a umbrella kept the heat out when we used it one summer but don't care for the trouble the umbrella is to keep upright with any gusts of wind etc. So being able to hang the coolaroo fabric and or some of the other screen material may just do the trick. I checked the clips out and they well support and close on the fabrics just fine.
