Once again my friend Robin did much of the artistry, all of the baby cantaloupe and much of the cake. I decorated with baby outfits hung on a clothesline over the windows and on a clothesline outside. I hadn't done a buttercream cake for a long time, so I had forgotten that I needed to make a crumb coating, but other than that I was pleased with the buttercream recipe I used. with coffee creamer suggestion in comments. (might try this one next time) The bubbles are gelatin with powder dust. (tutorial here)
