This is not a rare occurrence and as flattering as it is to be asked, giving advice for a space you usually have not seen is at best tricky.
Hence, this column:
I will post general advice in answer to non site-specific questions I have been asked.
You may participate, of course.
That would be so much fun.
Just keep it relatively general, if you could.
Melanie: I need to add a railing to my new stairs. I am debating between geometric and curlicue. I don't want too classic and I don't want too crazy. Any suggestions?
There are many possibilities which will fit the bill. I suggest keeping the design simple, even in the case of curlicues. You may also want to avoid historically faithful reproductions if you wish to keep your space style-neutral. I would leave the Louis XV to very old houses and chateaux. There are many other ways to stay a little classic and have a little fun. You may even want to mix some straight lines with some wavy ones, as is the case in Provence very often.
Modern curlywurly. Fun for a modern space.
