I enjoy creating Sunset/Sunrise cards! "Enjoy Life" Stamp Set #148190 is a lovely silhouette stamp set to use with this FUN technique.
Here is my process which allows me to reproduce the same card multiple times:
*Punch or die cut a generous shape in the center of a quarter sheet of scrap cardstock.
*Lay this template on your cardstock and hold in place. (I just use my fingers.)
*Using a Sponge Dauber #133773 pounce on an ink pad to collect color, then scrub ink into the opening of the template, using a horizontal motion going beyond the edges of the template. Blend one color into the next if desired.
*Mark your colors for use at a later time and keep in the template in your stamp case.
*Stamp a silhouette in black ink within the window before removing the template.
This is a lovely, thoughtful sentiment! Try sponging a Sunrise/Sunset!
