... for my sister's first baby shower in 1998. It's supposed to look like a mobile, with the letters of her baby's name "C-L-A-Y" dangling from the top tier. Adorable. The top tier was a "dummy" made of styrofoam, because I didn't need that much cake, and I was afraid actual cake wouldn't hold up those sticks.
... for my aunt's co-worker (years ago). I love making the keepsake booties from marshmallows and royal icing. My Aunt Cyndi used to make them for many of her baby shower cakes too. They dry and harden, and they can be kept forever.
...for my other sister's first baby shower in 2000. It was supposed to look like a quilt, but the colors came out much brighter than I had anticipated. I made the little figures on top from candy melts because I hadn't discovered fondant yet.
