indecision in dining

The bedrooms and bathrooms are coming along.  They're much closer to being ready.  I'm not going to show you any more pictures of them until they're totally completed.  Hopefully the "suspense" will make the final outcome more exciting.  They would be totally done right now, but we are playing a lovely little game that's called try to fix the border between the trim and the walls.  Aka our painter's tape didn't really work, and now we have wall color on the woodwork.  And then, when we try to paint over it, we get woodwork color on the wall. It's a vicious cycle and quite frustrating.

So, instead of thinking about that, I'll daydream about the dining room. But I need your advice.  Those of you who know me, know I can barely pick out what to eat off a menu or what to make out of a cookbook, let alone what color to paint a room. It is still a total blank slate.   White walls, white trim, mismatched furniture. This doesn't help me at all.  I know I need to re upholster the mismatched chairs and paint them all the same color.  But what color? Where do I get fabric from? Would you want a dining room in a bed and breakfast to feel formal or casual?

Does the fact that it's drapery fabric mean I shouldn't use it on chairs?

Chandler Spice Multi-Purpose Fabric

Multi-Purpose is a better sign, no?

  

this, this or this? 

  

Love these three from Pottery Barn.

And these from Maine Cottage are unbelievable, but a little out of my price range. Maybe some day...

I want to pick out a fabric and then try to match wall colors from there. I know I tend to lean to blue and green for everything, but I've heard that the color blue can actually suppress appetites, which I obviously don't want. Red and green supposedly promote them...hence why almost all grocery stores and fast food chains feature those colors in their logos.  What do you think?  Which colors would you choose for a dining room?
