building a nursery

I am going to have a new nephew soon!! My sister in law (brother's wife) is on the way and is due to give birth in July. I have promised them that I will spruce up the nursery and will make sure that it's going to be a room fit for a boy so as early as now I am searching for the best Window Blinds that will suit the color of the walls and matress. I am so excited that all I do the whole day is to search for things that I will be putting in the nursery. Any suggestions?
