Recently I added tan as an embellishment to a sky blue page. I loved the soothing restraint of the two colors. Play with them. You can erase chalk from die cuts, so anything you try with chalk can be undone. Use the indented lines on your die cut as guides for adding a thin, thin line of penned in ink.
Wider letters are easier to pull from their non-stick backing without tearing.
Lay a piece over any brightly colored paper and see how the hues are tamed. You can make an outrageous and domineering piece of paper into a pussycat by adding a layer of white vellum. Don't wait for an uncooperative computer to force you to take a chance. Scrapbooking is playtime for adults. Be bold, be daring and be different.
