You might not know the difference between a world class master piece and something that Joe Bloggs has knocked up in his garden shed, but a professional framer certainly will be able to tell the difference between the varying types of artwork that you ask to be framed.
Whatever you are framing, you still need to pay attention to the quality and finish of the frame and mount you are going to be using. Although you can easily pick up a frame in any high street shop, you are not going to get the finish and the service that a professional framer will be able to provide for you.
A professional framer has a wide selection of ready made frames that you can choose from when you are looking to frame a piece of artwork. If you are unable to find a ready made frame that is suitable for your particular piece of artwork, you might want to consider purchasing a custom made frame.
In addition to custom made frames, you may also require a custom made mount in order to ensure that your artwork and the mount fit inside the frame like a glove.
