Green gallon jugs have wine in them, I've gotten them from restaurant trash or by asking them to keep them for me. Don't think any wine comes in brown. Try going to a bar and asking them, they might know what comes in those bottles, which would give you a guess of where to look.
Vases: Go to the flower shops, quite a few of the non-chain ones take back vases from people, or end up with them leftover from
yard sales etc.
There is also glass paint you can buy that makes fake stained glass, it's easy to work with, could just paint the clear ones. I've used the brush stuff, looks like there's spray paint too, which might be easier.
:D
And, if you decide you want to buy some,
