I bought some glass bulb ornaments at Hobby Lobby when they were half off. ($4 for 12 bulbs)
We filled them with fake snowflakes.
I wrote the kids' names on them with a paint marker and the kids picked out snowflake stickers to place around their name.
They turned out well and were much cheaper than buying professional, personalized bulbs.
They looked really nice with just stickers on them as well.
