These are diaper pins to wear at a baby shower. Every guest gets one. One diaper has a sticker inside labeled "dirty". I put a larger pin on that one so I know it gets handed out. Whoever gets that diaper (everyone opens theirs up to check for the sticker) gets the door prize.
For my daughter's first birthday party, I made her into the "Gerber" baby by creating new "labels" for the jars. I started with a Word document and inserted a picture of her from my Kodak files . . .
