I was recently asked a question about the difference between using the pastels and inks with a sponge dauber. So I decided to demo it! :o)
Over all, the pastels give you a softer affect and a more blended look. The inks, while just as fun to work with, are more crisp.

Here is a close up of the "poppin Pastels" technique. There is a great tutorial on this technique here at SCS. Basically, you stamp your image in Versamark ink and then use a sponge dauber to dab your pastel color onto the image. The funnest part of this technique is seeing your image come alive right before your eyes! :o)
This is the same technique used with the classic inks (It will also work with the Craft - but will need to be heat set or embossed). The only difference is, I picked up my color with the sponge dauber on the ink pad and put it directly onto the stamp. Once I applied all my colors, I then stamped the image. This one can be a little tricky, because you don't really see the full result until you actually stamp the image. But I love the element of surprise! :o)
Supplies used: Medallion Background Stamp; Versamark Ink Pad; Stampin' Pastels (Ruby Red, Old Olive and Summer Sun); Classic Ink Pads in Ruby Red & Old Olive; Sponge Daubers.
