Decorating your home can be a daunting prospect – all those white walls and empty spaces with nothing to fill them with yet.

As tempting as it may be, don't be seduced by a quick fix, you'll probably regret it.

Here are 11 common mistakes you should avoid at all costs…

1. Buying everything in one day

Shopping for an entire room’s décor in one day is not only stressful, it's an all-round bad idea. Very bad idea.

You run the risk of matching and you don’t want to do that – take your time, aim for a layered decorating process. Build the look and feel of a room.

2. Buying furniture before measuring a room

Sounds silly doesn't it, but In the whirlwind of ‘we just bought a house’ excitement, many homeowners buy items before they’ve even moved in. 

Rather than making buying decisions based solely on a floor plan, live in your space for a while.

3. Picking pale paint

The larger the space you're painting, the more tonal depth your wall colour needs to have. 

If your home features an open plan, when deciding on the main colour, select one that's slightly darker than you'd normally choose for a small room.

4. Buying area rugs that are too small

You should allow for a 12- to 16-inch border of flooring around a room's perimeter; anything smaller, and the rug will look too insignificant.

The front legs of your furniture should sit on the area rug, so the rug doesn't appear to "float" in the middle of the room.

5. Opting for no bed headboard

The head of the bed is the focal point of any bedroom, but many people tend to overlook the headboard.

If you don't have one, try an eye-catching artwork or a decorative tapestry – or paint the wall behind the bed a dramatic colour.

6. Decorating without help

Decorating is costly, difficult and emotional (has no one else ever cried over gloss paint?), so why not invest in the help of a professional? For a small percentage of your overall budget, you'll have the guarantee that your project will look great for years to come.

7. Buying too many small accessories

Step away from that cushion! Forgoing trendy accessories for a year or two could save you enough money to buy a substantial piece of furniture you'll have forever.

8. Hanging frames too high

The bottom of the artwork should be eight to ten inches above the top of a piece of furniture, be it a headboard, sofa or credenza. In a hallway or stairwell, hang art so that the middle of the work is 66 inches from the floor or steps.

9. Not making the front door the focus

Don’t be afraid to add a pop of colour to your front door – you want to make a strong first impression.

The front door should be the first thing visitors see; the garage door should be the last, so paint it a similar colour to that of the house.  Paint the front door a complementary colour so it stands out.

10. Displaying collectibles all over the house

Dotting them all around the house only lends a cluttered look to your decor. Instead, create a big impact by grouping a collection together – either frames on a wall or figurines on a shelf.

11. Having more than one focal point in a room

Every space has a focal point, so try not to blur the lines. In the living room, the focal point is usually the TV, sometimes the fireplace (whichever you enjoy most, no judgement here). In the bedroom, it's the headboard; in the bathroom, it’s the vanity area.
