With the configuration of the HVAC register, I don't think drapery are in your future. They would have to be mounted so far out from the glass and that look would just be bad.

If you want to remove the blinds, they could be replaced with a softer shading solution like Zebra Blinds.

I hate fake drpe panels IMO you either add drapes 2 or 3 times the width of the rod or no drapes .

Hi Maddie-

Congrats on your new place!

You can go without the curtains altogether.

Film:

If the sun is an issue, you can get a film to cover the windows and door to block UV and bright sun and there are many options to choose from.

You can pick one that will prevent fading of upholstery and wood and prevent you from roasting and losing heat, but will not darken the room or block your view.

As you will be saving money by not purchasing curtains, please buy a quality product and have professional installation.

Homey:

You can have your room be more "homey" by changing the decor.

It is difficult to see your room as your photo doesn't show much of it.

Also, can you please describe a little more what homey means to you, perhaps put up some rooms that you love so we get a better idea of what you would like your room to look like, feel like?

If you add more photos of the room and from different angles, and the adjoining spaces, we can offer more suggestions as to how to make the room more "homey."
