Whether you're looking for a card for a baby shower, for welcoming a baby, or any other baby event, why not do a onesies card? Onesies cards can be just as cute as onesies themselves. I've decorated my onesies cards with patterned paper, and a small baby-related pattern on the belly. We could also do sparkles, ribbons, buttons, rattles, you name it. You may have noticed that I also like to have messages inside the cards.
