Minted is one of the card companies I recommend for printing birth announcements, they have a great variety of designs from a wonderful assortment of designers. You can check out their website here http://clarefisherphotography.minted.com.
Today they sent me a link to some of the new shaped cards that they have as well as a couple of Pinterest links. If you’re looking for some nursery ideas or even some cute ways to make some pieces of furniture work dual pupose (great for all our New York City living quarters) I’d check out this link. http://pinterest.com/minted/modern-nursery/
