Set your equipment up as above and divide your paper up into sections with the masking tape, around the edges, horizontally and vertically. You are now ready to begin painting.
Wet your largest brush and brush over one of the squares of paper. You want the paper wet but not soaking. Then dilute some paint with some more water and brush over the wet paper. Start from the top to the bottom working from side to side. You are just looking for a pale wash of colour at this stage.
Continue to work in this way for the rest of the sheet of paper.
When all the sections have been painted leave to dry.
The next stage is to add your painting. I have shown two imperfect images above. You will be able to do much better than this! The idea is to produce a 'flower like' image. With your chosen colour of paint, load your brush with colour and quickly dab on the paint to form a flower type shape. Whilst the paint is still wet, pick up another colour on your brush and add to the centre of the 'flower'. Don't try to move the paint around. Just let it bleed naturally into the other paint. Whilst this is drying move on to one of your other backgrounds and do the same. It is surprising what effects you can get. The results of watercolour painting are unpredictable!
When you have completed your designs and the paint is dry, remove the masking tape.
Using a guillotine or paper trimmer cut between the paintings.
Because you masked off the paper you will have nice clean white borders around your work. I enhanced the border further by edging the cards with a Sakura Pen-touch gold calligrapher pen.
