Let’s talk about some sketchbook drawing ideas arranged by theme. To draw something about still life you can chose to draw a traditional setup of dishes, fruits with tablecloth. It will be great if you experiment different arrangements and doing thumbnail sketches of each. The second idea can be to arrange a few stainless steel utensils on a black background, then draw them by using a tonal study in graphite pencil.
Or you can try an artistic drawing in which your drawing suggest a story that has happened or is happening. You can draw a bloody big or small knife, broken objects, historical items and photographs, clothes on a table or chair and in this way you can present your drawing objects which can be loaded with meaning. While trying the drawing ideas play with contrasts of old or new, dark or light, spiky or soft by using objects and fabrics.
