An original work of art is a great value and it can also bring fresh atmosphere to a room. When you have visitors over, it can be a wonderful talking point! So make sure you hang it where it enhances the room atmosphere, and where everyone can see it clearly.
If you have a good sense for decoration, you may already have a picture in your mind where to hang your new painting, what frame to put around it and so on.
I would certainly be delighted to help you with your decision making. So, if you are planning to buy, or have already done so, please give me a call. I would like to hear about your ideas, and you don't have to follow mine.
If you can afford the services of a professional interior designer, by all means do so. Their opinion may give you peace of mind.
If you are looking for ideas: magazines are full of photos of tastefully designed and decorated rooms. There is also a wealth of information on the internet. Another good source for ideas is your favorite furniture store. Their wares are usually laid out in attractive ways to make it look best.
Finally, when you have the picture hanging, look at it from different angles and vantage points. Does it get enough light? Is it hanging where someone can stand easily and look at it? Is it hanging where it could easily get damaged? Trust your own intuition and imagination. Life is a great adventure!
