Some effective drawing tools are ink pens, chalks, paints, crayons, pencils etc.

Some tips which would be helpful are as follows:
1. Make sure you draw from real life and not restrict drawing only from photographs
2. While beginning to draw, less is always the key to being successful. Do not go into very minute details, especially when you are a beginning.
3. The entire process of drawing need not necessarily be completed in one sitting. First make the layout which gives the general idea of the drawing and then go about adding more details.
4. Do not judge the drawing even before it is completed. You could easily get discouraged and there are chances that you might give up, even before completing the drawing.
5. Start with simple topics, so that that you are able to complete it and do justice to it. Picking up complicated topics would force you to leave the drawing midway and you would soon lose interest.
