Curtain holders

When my windows are open, the wind outside sucks my curtains into my windows screens. I also wanted my curtains to stay fully open at the top to get the maximum amount of light in my room during the daytime. I made a little holders that stick on the curtain poles to hold the curtains open.  I did not want to add additional holes to my walls, so I needed to have a non-destructive, no hardware system. By no means is a perfect system. There is a bit of wiggle room on the holders, but this doesn't feel flimsy when placing the curtains over the holders.
