Here is the card I made for the challenge:
I stamped the image of tower bridge by Artemio Stamps in black versafine. I then used distress markers on my craft mat mixed with water to colour in the image. The distress markers I used were vintage photo, antique linen, black soot, stormy sky, chipped sapphire and fired brick.
I torn the top and bottom of the image while the card was still a little damp as I thought it would be easier - I was really worried about tearing it at this stage as it had taken me so long to "paint" it and I had visions of it ripping right down the middle! I layered up the image onto black card and torn the top of that too to match the top of the image. Around the bottom of the black card I added blue and white bakers twine to try to continue the water theme (well that's how it was imagined in my head anyway!) The sentiment is from waltzing mouse and is stamped in black versafine also. To finish off I added the little blue pearls either side of the sentiment.
I hope it is clean and simple enough for the challenge as there isn't too much white space now that it's all finished compared to how I had imagined it when I started out!
