I would add a high-end piece of silk to the head board. Something like a Tai silk with its own weave/pattern. Staple it onto the back of the head board to see what you can come up with. I bet that would start the whole ball rolling.

Do you have a picture
Of what you mean? My husband built our whole bed and headboard actually!!

How cool your husband is so handy! If you want a wow, I think chandeliers hanging above the night stands looks wow. First, I'd suggest getting two more curtain panels so you can extend the rod to have your curtains line up evenly with the edge of your headboard. Having a ceiling electrical box would be required but it's worth it. I like the wall color you have.

Pinch pleat gray? Target at a great price...

Check out the above headboard. Maybe your husband can get strips of the nail head detail and nail around the edges like the above photo? If you like the look.

Great idea!!! Thank you

Is that the only window in the room?

No there's one on the side of the room

I would do something like tufting to the headboard. Blue could go great with this room.

Example of tufting

I was thinking blue also!! The tan is too plain for me!! What color bed spread and night stands?

Bedding like this would look nice!

I would hit the post Christmas sales to get a duvet cover, then get other colours from that.

Pick your bedding or headboard fabric first, then wall color.

It's disconcerting to have the bed in front of the window - will it fit on the other wall?

Drapes are too thin. You need at least double the amount of fabric. Hang them high & wide (mainly outside edges of the window). Your lamps are too low for reading. Consider some wall-mounted fixtures.

What is your style? Please post some more pics of other rooms you have and/or like.

space planning could be a good start. the bed should be on a wall with no window, and new larger scale lamps!!

Some ideas. I would add nailhead trim to your headboard

You have a nice start with the cool bed....continue the bed with a duvet cover in one of the colors in the curtains for a nice coordinated look. Don't forget to put a fitted sheet on the box spring that works with the duvet cover so the box spring always looks 'designed'.

Add a large piece of art for one of the walls with colors that include the bedding/curtains......check out Alexa Hampton interior design ...she does great compositions of smaller art combined into a great looking whole design.

Add lamps in a contrast color or coordinating color that are as tall as the headboard or a bit taller....this will be expensive as bigger lamps have a bigger price but you need them to balance out the large window, curtains, and headboard....now take a breath and see how it all looks.....

These are all the elements mentioned above but two very different rooms.
