We need to find a blackout solution that is more like blinds or roller shades, that fits inside of the window frame. We have curtains on the outside now, and I want something that's really easy to open/close when naptime is over. Do you have any you love? We're renting, so I'd like to spend less than $25 per window. And, I want them to be pretty light-proof - the room is on the west side of the house, and gets a ton of afternoon/evening light. Links appreciated.
