check out the websites for the tv shows you're interested in.....HGTVs new show "HGTV'd" is looking for homes.
Beyond that, check your local listings & also rely on "word of mouth".
EDIT: okay, it's naptime, I can give you a longer answer! My living space is open concept. Our front door is inset btwn 2 gables. When you walk in, you can go to the right to the bedroom hallway or left to the open living space.
As you enter the living space, you are in a foyer area which we use as an office/computer area. The electronics are in a huge antique cabinet. This is mainly a pass-thru area, & from there you can enter the living room or head to the dining room. The kitchen is open to the dining room.
When you stand at the front door & look into the living space, all of the walls are the same raspberry/cranberry color. I chose this color to blend with the fireplace wall in the living room - it is a full brick wall. There is only one other wall in the living room. The dining room also has only 2 walls. As I mentioned, all of these walls are the raspb color.
The interior walls of the foyer are also raspb, but the exterior wall (the one with the front door...which leads to the bedroom hallway) is a soft terracotta. Normally, I would not combine a rich raspberry with such an earthy tone, but there's enough color in that terracotta .....that it all works well & I've received many comments on the color combo.
Now for the kicker, when that front hall hits the corner & turns towards the rest of the bedrooms.....the walls change at the corner & are a handwashed Tuscan yellow. A very soft yellow, hand-glazed with burnt sienna. While this may sound dated, it is simply "classic" & works well with the terracotta. The soft yellow is a perfect backdrop for my collection of family photos!
Because I have used a very rich color in the living space, I chose to go with white wood shutters.....the old-fashioned kind, not blinds. The shutters are on the lower 1/2 of the windows. The top of the windows are draped with simple white wrought-iron rods & plain muslin sheets. Yep, sheets - not actual curtains.....& nobody knows!!! They're cheap, they're almost maintenance free, & look perfect. I created a rod pocket using antique bottoms sewn across the width of the sheet. This little bit of "bling" amps up the "look".....& is so easy to do!! The white on the windows offsets the deep color on the walls. This white combo is on all of the windows & both glass doors. I live in a house full of men & big dogs.....& the white is never an issue!
The furniture is a combo of soft sage/celery greens for the curved sofa & DH's recliner, we have 2 Craftsman/Stickley-style burgandy leather recliners with rich mahogany wood frames, & we have a matching antique sofa & club chair upholstered in all-over floral/vine motif....in the greens of the other furniture & the raspb of the walls. Even tho' it is very eclectic in element, it all works because the room is pulled together with antiques & treasures of all different periods....including lots of flea market oddities.
Currently, the floor is a hideous variegated brown carpet. I HATE it....& after living with it for 20 years....it's on it's way out! My thought is to have oversized slate tiles for the square part of the living room, with wood thru the dining & foyer areas.....& then running down the hallway. That's the optimal plan....but it looks like it'll be wood thruout....we'll see!
Good Luck & make it FUN!!!
