Cordwood construction is a method of natural building that originated roughly one thousand years ago in Greece and Siberia. This method involves using pieces of wood that slightly protrude from the mortar, giving the walls an attractive appearance. Usually, the walls are made 12 to 24 inches thick. However, in some parts of Canada, the walls can be as thick as 36 inches. This method appeals to many people due to its ease of construction economy of resources. Cordwood Construction can be separated into two main types: mortar-insulation-mortar (M-I-M) and Throughwall. M-I-M is a more preferable and widely used choice as it allows for better insulating properties.

The combination of two different drawing styles in one picture never ceases to amaze us. The works of Allison Kunath are a vivid example of this technique. The background of her pictures is drawn using watercolors, while the actual image is broken down into rough geometrical shapes. This creates a very striking contrast, thanks to black, bold lines of the image on the forefront drawn over soft, cloudy shades of color. The skill of Allison is clearly seen in the way she manages to draw something as amorphous as a squid without making any curved lines. (Photo by Allison Kunath)

Do you ever get the irresistible urge to light matches on fire, especially if there are many of them in one place? If you do, you shouldn’t come near the giant globe made by an American artist Andy Yoder. The thing is, this 42” globe is made entirely out of matches on the outside, while the center was made using plywood, foam, and cardboard. It took Andy two years to complete his work, finally finishing in 2014. Each of the matches used was hand-painted and then glued in place. Also, in order to prevent his masterpiece from catching fire, Andy Yoder has doused his work with a flame repellant.
