Thought I'd share what I've put together so far:

The bottom right tree is a wall-sized decal that I'll get in a taupey color and have behind the crib. And here's what I'm still deciding on:

Supposedly, the blue drapes on the right are the same color as the blue
in the rug (above). If that's true, I like the patterned drapes, but
then feel I should go for a plain crib skirt and sheet (although I'm
not sure the one in the picture is the right blue). If the patterned
drapes aren't the same color, I'll probably go for the taupe drapes and
then I like the patterned crib skirt--and I think the one pictured goes
pretty well with the rug. I'll still have to see how everything looks
in real life, though. What do you think?
Re: Inspiration Board
I love what you put together so far, and I like the idea of the patterned drapes and a solid crib set. Where did you find the tree decal? We'll be in an apartment and won't be able to paint the tan walls, so that might be a good option for us.
Thanks!
