Add a piece of painter's tape to the watercolour paper. Press down on the length of tape to make sure it's secure on the paper. (So paint can't get under it).We're going for a random stained glass look here, so you can add the tape at any length and any angle.
Continue adding tape until you're happy with the design. Keep in mind that the tape parts will stay white.
Add a Tablespoon of water to a small cup or dish.
Add 5 - 6 drops of liquid watercolour paint into the water. The more paint you add into the water, the brighter your painting will be.Stir, and repeat for as many colours as you'd like.
Step 3: Add paint to the watercolour paper
Dip your paintbrush in one colour of paint and fill in a section of the paper.
Add the same colour to a different section, if you'd like, and then choose a new colour.Allow the paint to pool for darker areas of colour.
Continue adding different colours to each section until the whole paper is covered.You can also blend one colour into another in the same section.Allow 30 minutes to dry.
Once the painting is completely dry, remove the tape carefully.
