One of my favorite ways to add a subtle, and classy, design to my layouts involves embossing with my Slice. It's really easy to do and I feel like it's a "bonus" use for all of those fun shapes. For this technique, you will want the image to be raised, so you'll emboss on the BACK of your paper. Also, you'll want to use a printed paper (with a white core) for this look.
Simply insert an embossing tip into your Slice. Choose the image you would like to emboss - choose the size - and if you're wanting to add words, be sure to use the "mirror image" feature so they will be facing the right direction when you flip your paper over. Go ahead and emboss your design. Now, using a fine grit sandpaper or file, and lightly rub the design on the raised side. The color will be removed and you'll be left with a beautiful outlined image.
