Ideas?

Hello my friends! I have a new computer and I am in the process of getting back online. Slowly but surely...

I want to pick your brains. Although my baby is almost exclusively breastfed, he occasionally gets feed some formula that we get in little glass bottles that hold six ounces. I have been washing and saving these bottles thinking they might be useful for a craft project. Does anyone have ideas for these bottles? I was thinking of decoupaging them and making little vases. Or jars of fairy dust? Or something for Halloween? I'll try to post a photo soon!
