I can't take credit for this idea, a friend of mine gave me a gift like this for my baby shower for my son, but I'm sharing this anyway!
The 'cupcakes' are made by rolling infant onesies into thin folded blankets, and then held together with a doily or coffee filter to look like a cupcake. Ingenius idea, if you ask me! Her's was SO cute I had to recreate it for a friend's baby girl shower! TFL!
