One of my projects for the kids at the farmers market this year was to take old wine bottles (I just soaked them in warm water and the labels peeled right off) and decoupage them. We used tissue paper, then wrote words on paper and add that (use mod podge). You can do poems, quotes, song lyrics,  or anything! I just used recycle tissue from gifts. They came out great! I also did it with a class once and we added photos of ourselves to them as well.

Oh, this reminds me of a project I did in high school. I think it was like to learn about color, but we just did different little colors of paper (like a little mosaic), and decoupaged them (?) onto the bottle. So, the bottle came out to be just this pretty gradient of color.

Hi

If you were interested in lids for your bottles you can order them, also corks on line. If you did you could make your own bath oils, or give them as gifts. Or you could make olive oil infusions and herbal vinegars.

Here are directions on making a glass lamp - I didn't see a photo though which was too bad.

Mosaic backdrops are beautiful, something I've always wanted to get  into myself and have bottles  broken plates and shells stored, but the initial start up ( all the tools) is expensive at least for me.

Maybe you could do some mosaic on the bottles and make vases? I recently was reading some sort of blog online and saw this small mosaic 'plate' which was really neat because it had the mixed glass but also scrabble tiles to make up words.

you really don't need a ton of tools to mosaic. just some mastic, a hammer, grout is cheap....i did a whole bathroom floor and it was really inexpensive. I even got the tile free in the broken bin at the tile store. I save broken dishes and stuff also! :)  I mean you can get a glass cutter if you want to be exact, but I did my whole floor with just a hammer.
