I read an article about an artist called Tim Youd – who types out copies of books on one piece of paper. He over writes each page putting it back into a type writer to create texture and tone and abstract pieces . I really liked the idea of these so I am doing my own over doodle – drawing on the same piece of paper for a week
Day 1- I started with something simple to leave lots of space to draw over 
Day 2 ( with the start of day 3 ………) it was interesting how quickly I wanted to add a darker line into the design to differentiate from one day to the next
Day 3 – I couldn’t resist using the lines from the last few days to accentuate parts of the design today – I.e drawing into the flower bottom right using the lines in the page from day 2 
Day 4 – I am having to draw intuitively because it is begining to be difficult to see where I am going – I feel like I cheated because I out lined the flower I drew today to make it stand out. I know I am going to end up with a black inky page but – I found I wanted to establish where I took my pen for a walk today
Day 5 – I managed to use a slightly thinner pen by accident today and I told my self- no straight lines – the drawing is having to be intuitive and looser because I cannot always see what I am doing- I didn’t like it yesterday – to day I do – interesting to be making something that is not necessarily into asthetics , not thinking about composition , tone , line quality , depth etc .
Day 6 – I liked my end layer yesterday. I decided to keep the technique of drawing in a looser manner. I like it when something like this exercise which can seem quite randomn at the begining developes a skill or an idea- so I ‘scumbked’ over the top for today’s layer – starting in a small circle and then moving out – which follows the idea of the other days
I enjoyed doing it so much that I decided to add the technique to some of my travelling doodles – I like the effect of the looser technique over the top of my tight cross hatching

Have you read about David Hockney and how he kept running the same picture through the photocopier to build up the depth of the picture?
I’m going to have a go at the over drawing, thanks for the idea x
