It took my husband and I about 4 months to complete this nursery. Everything from handy work to decorations was done by my husband and I. He did more of the handy work, while I did some handy work and all of the decorating. I wanted my son's room to be simple, neutral, and not to much of a "baby's" room, but a room that can be easily changed once he gets older. Therefore, I went with very neutral colors: Navy Blue, Grey, Black, & White.
I really liked the chevron prints and safari theme for a nursery, but I didn't want to overwhelm his nursery with animals and stripes; I wanted to incorporate those two ideas together but keep it very minimal as much as possible.
Simple decorations that ties in with his colors is what I wanted this nursery to be all about.

My favorite items would have to be the fish mobile, DIY name plates that my sister made, & the glider chair (it is so comfy and just perfect for nursing my little guy).
My advice is to start with colors that suits you best and work with those colors throughout your project.
