If you have sheer curtains that you want to keep because for me, they match other curtains in the room, but you also still need to have your blinds on the outside for the HOA and you need a room to be darker. This is a great solution for you too! I used an inexpensive shade and a cheap tension rod both from Amazon and I’ll link those. You can get the shade and all different colors to match whatever shade your curtains are so that you can’t see it underneath. LTKHome
