Black will show dust.

Either will work fine but the black will have more impact.

Black!

I think black to show more against all the knotty pine. It should look great with the red and white you'll be using.

Black. Can't wait to see it when it's finished.

This is going to be one gorgeous guest room! I vote definitely Black, which will have a much better visual impact, IMO. OK, so let me know when the next girls' weekend is so I can pen it on my calendar (LOL).

Black and can I come over? My fave color is red so loving entire decor

Definitely black.

Black will look fabulous, what a great room!

Thanks so much, y'all! I like the black as well.

2 more things to pick your brains about.

Would you do a straight headboard or something with a bit of curve to it?

Examples-

Squared

A deep curve, (this comes in black)

And finally, what color for the nightstand between the beds? Red, white, black or wood like the armoire?

Oh, definitely the Deep Curved one . . . I love it!

Deep curve. It's going to look fabulous!!!

Deep curve and a black nightstand. I did a guest room in SW Jersey Cream walls, black iron headboard, white quilt with red throw, and red/white buffalo check drapes and bedskirt. I painted an antique table red to be used as the nightstand. The finish was terrible and a little chunk was missing on the lower back so I decided paint was the best option. We get so many compliments on this room.

Thanks everyone! Prairiemom, would love to see pics!
