Anybody have craft ideas for old wine bottles?

You can decoupage the bottles with pretty tissue paper and add some beaded wiring, I've included a link to project instructions which has great photos. These make good decorations and can hold liquids, like bubble bath, etc.

I also saw at a craft fair once, someone made cheese boards out of old wine bottles and liquor bottles. They must have had a very hot kiln to use, but they melted the bottle flat (lengthwise) so it was a flat wine bottle shaped cheese plate then turned the neck part of the bottle up to form a handle. They were so cool looking.

I've seen the green colored wine bottles with a hole drilled in the back at the bottom and white christmas tree lights stuffed inside. Looks pretty neat for sitting around decoration.

I agree with the idea of decor lights inside the wine bottels i have seen them and they are very festive

I saw Wine bottles that were painted and used for insence burners or for flowers

Dried/silk flower displays

Candle holders

Bookends

put flowers in them or put them on shelves with books.
