This video shows how to use Inktense Pencils by Derwent on fabric with water. The Inktense pencils become permanent on fabric, as an ink, when water is added. This makes them great for adding a little colour or shading here and there and only water and a brush are needed. An iron is helpful although not necessary to set the ink, once it has been wet and then dried it becomes permanent. Here it is being demonstrated on a year long project called Skitch a Day, a block of the day from www.gourmetquilter.com
