How to Keep a Sketchbook

Keeping a sketchbook is a great way of keeping track of creative ideas and getting in the habit of regular drawing, as well as being a useful resource for large works when you are feeling short on ideas.

Remember that not every drawing you do needs to be a finished work of art. You can use a sketchbook for rough notes, thumbnails and ideas, too. When you open your sketchbook, think about what your intention is for your drawing session. While trying something challenging is always worthwhile, simple subjects can often be rewarding. Don't feel constrained by what others think art should be about - make your drawings about whatever you find interesting, be it an unusual object, an interesting face, a beautiful landscape or an invented fantasy.

• practice drawing exercises:
  • do a blind contour then a contour drawing of your subject
  • do a negative space drawing
  • do some 30-second rapid sketches

Thumbnail Sketching

Shorthand Drawing for Artists

Thumbnail Sketches are Shorthand Notes for Artists:
Thumbnail sketches are drawing quick, abbreviated drawings. Usually, they are done very rapidly and with no corrections - you can use any medium, though pen or pencil is the most common. Thumbnails sketches are usually very small, often only an inch or two high.
Thumbnails are Memory Aids and Planning Tools:
Thumbnail sketches can serve as a memory aid to help you remember important features of a subject, when making notes for a painting or drawing. They are also useful when visiting a gallery, to help you remember important pieces. Ofen artists use thumbnail sketches to plan pictures. You can quickly experiment with format and composition, placing just the major features - such as the horizon and any large objects, and indicating movement and balance.
How to Draw a Thumbnail Sketch:
Imagine your subject or picture stripped of all details, through squinted eyes, or in poor light. All you see are big rough shapes and some lines. Thats all you need for a thumbnail. First, sketch a rough box, smaller but in the same proportions as the finished picture might be. Then sketch in the horizon line, hills, or any major verticals or horizontals. The outline any key shapes, and quickly hatch in any strong dark areas. There are no right or wrong ways - that's my approach, and it might work for you.
Thumbnails can be Colored:
Thumbnail sketches are a great way to plan color schemes. Use textas, colored pencil or watercolor to put in major areas of color in your picture. Small but intense colors can also be noted, as these can attract the eye, but don't get bogged down with detail.
Making Notes and Working Drawings:
Once you've done your thumbnail sketch, you might want to make some notes alongside it. If at a gallery, you can record the artist's name and the title, along with your thoughts about the painting. If sketching outdoors, you might record notes about the position of the sun, the particular colors, or make additional sketches to show small details. If you are planning a painting, you might want to do a working drawing. A working drawing is usually fairly large, sometimes as big as the finished piece, and carefully composed. The subject is sketched in, and potential problem areas might be done in more detail. This is where you can fine-tune your drawing before embarking on the finished piece.
