Watercolour flowers with Kuretake Calligraphy pens

When I was at a recent show many people loved the calligraphy pens but they didn't think that they would be clever enough to use them for writing. So here's another use for calligraphy pens that needn't frighten you.
First of all you'll need at least two calligraphy pens in toning colours. I've used a light and a dark one from the Heart pouch set.
What I then did was touch the side of the lightest pen with the dark pen.

This will allow you to write in two colours.

I kept the darker edge of the pen still and moved the light side in a rough quarter turn and got a petal. I then moved the paper a bit and repeated the above. I did this until I got about 5 petals. Just remember to move the paper round every time you want a new petal.
