I used Distress Ink Walnut Stain to stamp all my images. I had no intention of doing a no-line colouring but I didn't want the lines to turn out too sharp like if I use black ink. And I kind of like the vintage look that brown outline gives.
You notice that I did not stamp any of the images right in the middle. I wanted to give the tag a big of "movement" and some added interest without adding layers to the tag. Try doing this to add image you have for your next project and I bet you'll like it ;)
Once your image is dry, all plenty of clean water around the image and drop some colours and let the water spread the pigment out. You can help it by using just a clean wet brush to push the colours away. This gives a soft "halo" to the image.
