Girls Coral & Aqua Inspiration Board

We decided once Phoenix was born that we would re-do Emmi's room.  With all the attention P is getting we want to make sure she is getting something special for herself.  I want her to be the "client" and have a say in what her room will look like.  Since what she wants and what I want (I'm sure that is going to be a theme with the two of us until she is in her 20's) are almost opposite, I decided the below inspiration board would be a good compromise.  She asked for purple, but as I've said before our ENTIRE house is wood.  Dark wood.  Purple will just be too dark. 

Here is what I came up with..with approval from Emmi of course.

1-Paint swatch from Pinterest with broken link.  If this is yours let me know and I'll give credit where credit is due!
2- I painted this dresser for my sister and I hope to find something similar and paint the same color
3-White Duvet, 4-Chevron Blanket, 5-Rug, 6-Owl Frame, 7-Coral tray, 8-Lampshade, 9-Painted Headboard (will do something similar to a 2nd hand piece I find), 10-Coral Box, 11-Zebra Head

I think this is a good start for Emmi's room.  Sarah Richardson, who is one of my favorite designers, gives great advice on decorating children's rooms.  She always designs rooms they can grow into.  That's great for the budget too.  As they grow older you can switch a few key pieces at a time and save some money rather than redecorating the entire space every couple of years.  This is one of the main reasons we did not buy Emmi a toddler bed.  She is going from crib, to crib with one side off to full size bed. 

How do you plan out a room?  Do you start with one inspirational or existing item and build from there?
