I just finished decorating last week with Command strips, and wow! was it easy. We have a lot of humidity in our church and the Command strips always hold anything I have to hang. I had styrofoam clouds on the beams on the ceiling and they stayed put. The styrofoam clouds on the cinderblock walls stayed intact. and the Clouds of cardstock and cotton stuck to the cloth Shower curtain sky for the backdrop. The posters were put on the cinderblock wall with Command Strips,along with the hanging animals and parashute, and the clouds on the sky fabric in the hallway was hanging up all week. Thank you for such a wonderful product, I couldn't decorate without it. When I removed them, no paint came along, the painter is happiest. Thank you for a wonderful product.
