In this video from Castle Arts we show you how to control your drawing edges by using thin and hard edges to give the subject definition and a solid border. For this example we use blue-barrelled pencils in B, 2B and 4B, paper and twin-tipped blenders, kneadable eraser and sanding block, all contained in the 40 Piece Set. You can also download an A4 PDF tutorial which guides you through the techniques used. The PDF also includes a pencil outline of the horse used in the video so you can print out and practice as many times as you like. Once you've completed your shading and blending, upload to Instagram using the hashtag #castlearts, we would love to see and share your artwork. Enjoy!
