If you are using the QuicKutz goosebumps or the Cuttlebug die folders this tip will work for you. On your solid color cardstock gently swish a swash of acrylic paint across an area. You do not want it too thick because thick paint will prevent the embossing from taking place. Let the paint on the paper dry thoroughly. Then insert the cardstock painted side up and emboss following the specific instructions of your particular die machine. Take the embossed cardstock and lightly sand the top of the embossed elements. It will give you nearly the same results as the white core cardstock except it is in two colors instead of color and white.
