B2 (used for the line art)
B4 (used for the re-enforcing the line art -where needed- and for lighter shading)
B6 (used for the stronger shading and also to help with the blending of tones)
A good way of using this combination (when shading) is by starting with B2 laying the indicial lighter color shading, then add a bit of B4 to darken the parts that should have a median shading, finally use the B6 to fill in the very dark areas. Remember not to apply too much pressure to your pencils. So, that you can avoid unwanted marks.

Also, for blending the colors you can use; blending stumps, tortillos, chamois cloth. Unfortunately, however, I did not have any of them so I used… my wife’s make up brush to blend the colors. Then, after she got upset with me I gave up on her make up kit and took her painting brushes.

So as you can see we can always get around the absence of a tool and yet achieve a nice result.

* Do not use your fingers to blend colors… Our skin has oils that can damage the quality of the paper and with it the drawing.
However, feel free to experiment with all the pencils and tool available as soon as you are able to get them. There is a big variety of them so you can try them all and see what brings better results. I think that the secret of drawings is held by those who know how to use the tools they got to get the best possible results. Though, don’t let excuses stop you from drawing… Excuses just keep us from achieving our goals in life. Remember, all what we need to draw… we already have within ourselves, so let us use it.

I hope that I answered your question my friend. Oh! besure that I would love to see one of your drawings.
