Summary

After getting my windows repainted, I was loathe to drill new holes in the frames. Originally, I used command hooks, but the adhesive isn't strong enough to hold up a curtain frame. I designed these to sit on the top of the window frame and the command strip just holds it to the window, which is much easier to manage.
