You could take said bibs and onesies and clothes-pin them on to a piece of rope. Decorate the pins with little pink or blue baby things (can find at a craft store like AC Moore). Arrange the clothes line with things attached in a basket or a hamper so when mom starts at one end the clothes will unfold, so to speak. I dunno if that makes sense but it's a really unique way to recieve a gift.
At a baby shower a few years ago, we had all chipped in for onesies and bibs and decorated them ourselves, then wrapped them and gave them all to the parents. It's a practical gift but a little more personalized and fun than happy little bears and bows.
I had also seen a website that showed baby stuff, like bibs, onesies, receiving blankets, etc., folded up into animal shapes. The eyes, mouths, ears, wings and feet were rattles and pacifiers. I'll do a search for the page or see if it's still linked in the bookmarks on the other computer and edit this if I find it.
