In this charcoal sketching set you'll find both willow and compressed charcoal sticks, with both producing very different effects when used. Compressed charcoal makes a fine, hard line that is great for drawing detailed sketches, and these sticks can be sharpened and shaped to your preferred thickness. Willow sticks and soft and thin, and so great for making line art and designing the base layer of a more complicated piece of art. Use both of these charcoal types in conjunction with the provided blending stump to soften and smudge your lines for different effects and patterns. Finally, keep them all safe and secure inside the compact storage tin included in this handy pack!
