For now this will be a collection of ideas/plans, but I'll post pics once things start coming together.
Bedding:
Wendy Bellissimo's 'Argyle'

Trying to decide on paint colors:
or 
Blue Hydrangea Blue Jean
For reference, Blue Hydrangea matches the light blue color in the bedding exactly, Blue Jean is one shade darker on the same swatch.
For curtains, I'm thinking:

(sorry, it won't let me save the picture, just the link).
Our crib & changing table/dresser are natural maple. The glider is slightly darker finish and is covered in a dark green upholstery. What does everyone think of the navy blue curtains w/the lighter blue walls? Too much blue? Also, should I go w/the lighter paint or the darker shade? Our bedrooms all tend to be really pastel-y, but I want something that won't look too 'baby-ish' as I won't want to repaint it in 2 years!
Also have an attached bath so would love to see suggestions for bathroom themes as well! I'm thinking something playful. The tile is sand colored, but the counter is blue silestone so I've been wanting to do a beachy sort of blue theme for a while now. This will also serve as a guest bathroom, but I'm o.k. with it looking very 'young' or boyish too.
