These one sided fans are, by far, my favorite of the fans I've bought from My Mind's Eye! The color is so delicate and beautiful. They are easy to assemble. I hang with Command Strip velcro on the wall and it holds all through the holiday. I do the same with the big, double sided fans too. I use the paperclip method vs the double stick tape to hold them together and it allows no damage to the fans so I can reuse them year after year. I have some fans that are 3-4 years old and look as good as the day they arrived.
