How to Arrange Artwork in an Artful Way

As I was searching Craft Sites and following up on Blogs I noticed this article written by Becky Harris, "How to Arrange Artwork in an Artful Way ".  She uses images as a great visual tool for pointing out just how creative we can be in attempting to update our art and collections displays.  Since Collections by Carol and Cards As Art creates the perfect opportunity to swap my art out each Season, I  always like to look for new ways to display my eclectic style, as well as help my clients find new ways to display their items as well.  As you can see,  I've also included a couple of images from my own home this Christmas to show you how I've implemented a couple of these ideas. 

Here's a rundown on several of the display styles of her featured eclectic group of designers that she  put together.  I attached a name to each of the styles I recognized. I encourage you to click on through to the original article and pics of the examples listed below. 

1.    Single Floating Shelf
2.    Multiple Picture Rails
3.    Mixed Media Wall
4.    Puzzle Wall - Matching size by height and width to pull together
5.    Black and White
6.    Eclectic - Matched by colors and shapes
7.    What's Different and Whats the Same - Combination
8.    Treating Collectables as Objects of Art

10.  Create a Shape:  Square, Rectangle, Circle
11.  Create a Grid
