Here's a SNEAK PEEK of the Core'dinations Cardstock, coming in the Holiday Catalog.  I hope you got yours in the mail!  Some really cool things coming.

I also used the Reason to Smile stamp set on the first one.  During July, if you place a $50 order you can purchase this stamp set for $5

So the Core'dinations cardstock (cs) is lighter in the core of the paper and it's textured on one side. so you can tear it or sand it to reveal the 2nd shade.
Here I have crumpled it and then sanded it.
