Each month there will be a new challenge set by a different artist. Images are
uploaded to Flickr. For January the theme is 'Highly Prized'.
I have been asked for a tutorial on one of the images I added, so here it is.
Bleach discharge as a sketch technique.
Colour you sketchbook page using ink. I applied mine with a piece of sponge.
I used a blue/black drawing ink, but try what you have.
Decide on your subject matter and make a quick sketch.
I cut sponge shapes using the sketch as a rough guide. I have used compressed sponge, which looks like sheets of thin cardboard but when soaked in water expands and has an interesting texture. You can, of course, cut up any cheap sponge.
Next pour out a small amount of bleach. You may like to wear gloves for this part.
Dab the sponge into the bleach and make marks on the coloured page.
As you watch the bleached surface will change colour, in my case from green to white.
Apply the bleach gently. Try not to dribble the bleach and beware of getting it on your clothes, as it will quickly discolour whatever it touches.
Additional marks may be made using a cotton bud.
The next step is get out your pens and work into the sketch outlined with bleach. Try out various pens and see if you can get some interesting results. My white pen resulted in an attractive blue line on the ink. You need to experiment here.
