For many years I thought that to make pretty lettering you needed fancy paints and large brushes and perfect strokes. This little project definitely disproves that theory. All you need are some watercolors, brushes, a pencil, and water. I used a sort of multimedia sketch paper, watercolor paper also works; as long as it's thick unlike computer paper, it will work.
Lightly sketch out your words if you feel the need.
Paint your letters with water; it should run, not just make the page a little damp.
Take another brush and wet the tip. Collect color with the brush and then dab in the wet outlines of the letters. Graduate the color - make some "focus points" and let it fade and become washed out in others.
When the paper has dried a little bit but is still slightly damp, take the paint brush and speckle the letters with watercolors with a drier brush.
Erase the pencil marks and add some embellishments with pens and such. Mine shall be a note to a friend of mine, a partner in crime.
Enjoy the creativity and the music, lovely people.
