Just sharing a card I made a while back. I haven't really played a lot with my watercolour pencils yet, but this card is one of those few times.
I first hand drew the circles with the pencils and then used the water brush to smudge out the circles.
After stamping the sentiment I took the water brush and used to tip of it against the tip of the pencils. The water then make tiny little splashes of colour on the card front.
Have a great day
