I love orchids - they are so exotic and gorgeous! That first picture is my favorite - and I love the table. Great find - you can get such great stuff on craigslist!... I wouldn't bother trying to paint it - it's beautiful just the way it is!
First--love the table! Second, your orchids are wonderful, my white ones just started blooming again, I'm so excited! I love the peach one...I think that will be the next color I get. :-)
Here's what I've learned about orchids: they don't like direct sunlight, but like a lot of natural light. They do not like being over water--I water mine ever 7-10 days, just put them in the sink, let everything get saturated and well drained. About once of month I give them orchid fertilizer. So far so good, I've had my white one for a year and half and it's bloomed three times! Good luck with yours. :-)
