I couldn't find an online pic of this...it ends up being a pair of baby booties. Very, very cute. And, really all that is needed on a baby shower cake.
Bootie Decoration Required: Large marshmallows, toothpicks, frosting, cake decorating bag, cookie sheet
Color the frosting into preferred colors for the baby booties. Each bootie will take three marshmallows and two toothpicks. Place two marshmallows on top of each other (flat sides together) and push a toothpick through them. The third marshmallow place next to the two with the flat side down and run a toothpick through the side connecting it to the bottom of the other two. Use a star tip and cover all of marshmallows with frosting this way. Ideas for decorating would be to cover in white and accent the edge with pink or blue frosting. Use a thin writing tip to create shoelaces and allow to air dry to harden.
