Must find a way to isolate the text more thoroughly or learn to paint up to and not over the lines :). I believe that others use some sort of masking fluid/pen, will find out. Tried regular masking fluid in another book and it took the print off - so not a lot of use.
Background is worked in watercolour pencils used as ordinary coloured pencils. The page was gessoed first which accounts for the irregular texture - an experiment.
