Clear, White and Aqua
Ok, so the first one is pretty simple. I stamped the background image on watercolour paper with Versamark clear and heat embossed with white Zing. Then I ran Broken China Distress Stain to give it a light blue background. The sentiment is from Hero Arts' Say It digikit (it's a lot cheaper than buying separate sentiments stamp, I tell you).
Second one is the same background stamp on watercolour paper. I used aqua Zing this time. And the background lime colour was actually done with my watercolour pencil. What you do is, you wet a painting brush with water and simply rub it on the watercolour pencil's point and then paint on the paper. As simple as that! The sentiment is from the same digikit.
For the third card, I coloured the water colour paper with Worn Lipstick Distress Ink. Then I stamped the background with Versamark and heat embossed it with Clear Zing. I couldn't decide which sentiment stamp to use for this card and decided to leave it alone for the time being. Hope you liked my cards. :))
