This week in my sketch book I used different techniques to play around with adding value. I drew three abstract designs and used crosshatching, stippling and scribbles to fill them in. I noticed that most difficult part with value is consistency. With pencil, for example, it is very easy to take a little break to rest your hand, or pick up the pencil and the level of darkness in your shading will vary. Also, stippling is very fragile as it is easy to do it quickly and the dots go from dots to a dot with a line attached to it, which in turn takes away from the effect. I think I would have enjoyed doing this more with a black brush-pen or thicker micron pen as it is more fluid; where as, the pencil made my hand stiff. I am now beginning to understand the importance of which materials aid better results, and which ones I prefer to work with.
