My grown daughter lives in New Hampshire and I live in Florida. She had an idea of how we could share some time together. She signed us up for an online drawing class! The class was offered through a local nature conservancy called The Harris Center. (Link at bottom of page.)
The mark made with a pastel pencil is not permanent and will need to be sprayed with a fixative (see more on fixatives below). These pencils are very easy to work with. There is a wide variety of strong colors available. They are perfect not only for finished drawings, but also for quick sketches and are especially effective when used on a colored paper.
Shorter, thicker, hexagonal sticks are also available in a similar range of grades, as are smaller rectangular blocks. Both types of stick are best sharpened using a pencil sharpener or with fine-grade sandpaper. The resulting powder can be rubbed on to drawings to create areas of tone. Larger quantities of dust can be purchased from art stores.
The Library & Archives here at the Natural History Museum hold original Waterhouse detailed pencil drawings and some chalk colour wash drawings. The collection consists of 136 mounted drawings and one volume of 66 drawings.
In this album there are 66 drawings, mostly pencil, but 10 have a colour wash applied to show the tone of the finished terracotta pieces. Over a third of the drawings are different from any of the master drawing set of 136, acquired in 1962 from Waterhouse's grandson. A further third are similar to other surviving drawings but show developments in the design process of the reliefs. Only 15 drawings exactly match those already held.
