Viva Las VegaStamps' Four Tulips image and Friends Are The Flowers sentiment.
Start by stamping your image onto the cardstock in black ink. I stamped my image twice, so that it covered the majority of the space. I also stamped the sentiment.
Next, use a grid ruler to line up a Post-It Removable Label to cover the left portion of your image:
Use a ruler to do the same on the right side of your card, using the post-it to keep the card in place as well. Be sure that you have "framed" a pretty portion of your image that you wish to highlight:
Because I wanted to use Distress Inks, I need to mask my image so that I could do the background of the flowers first. I simply stamped the image onto another post-it note, cut it out, and masked the tulips. I burnished all of the edges of the post-its with a bone folder - you could use a ruler or your fingernails, too.
Next, fill in the background of your image with color. Make sure to color right up to the edges of the post-its!
Remove the mask from the main part of your image and color it in, again, remembering to color right up to the edge of your post-its so that the edges of the spotlight panel are well delineated:
When you're done coloring, carefully remove the post-it labels... and have fun with the "reveal:"
And there you have it - an easy alternative to the traditional spotlight technique, and a fast way to add color without having to color your entire image. Hope you can give it a try!
