Book du jour - tissue, ink, and water

First, make your book - for these samples I've been working small, about 5cm square. This is a sheet of tissue paper (that happened to be floating around) folded and torn rather than cut. I drew lines with a permanent felt pen, first along one diagonal and on the next page along the other diagonal. There's some bleeding through the thin paper. Then, out came the spray bottle - 

 Left to dry (with a little help separating the wet pages) it looked like this -

Same method, but with a Muji calligraphy (brush) pen -

 To encourage bleeding, I put drops of water between the pages before inking the lines, but the spraying was all that was needed to get the ink to spread -

Not only was the ink not permanent, but it had a yellow component which leached out.

Different black inks, different colour compositions -- rather like the effects you get when discharging black fabric. Using bleach on various inks will be interesting.

And finally - the bag that the Muji pen came in - simply sprayed with water and left to dry -

It feels very solid.
