Anyone know where I can find.........Idea for my favors...HELP

I dont know where to look for them. I saw like different shape 'glass' (?) ornaments...like bells, Christmas trees, snowmen etc. My idea is this....Maybe possibly see how much the ornament alone is and then take them to get engraved with our names and our wedding date.
Now....where can I look for these glass things? Do we think Michales or AC Moore would have something like this??
