CTMH card stock has a white core middle...
Here is the shipping tag after I ran it through the cuddle bug with the swirl embossing folder and see how awesome the white core shows up when sanded.
Rip out a piece of pattern paper and crinkle really well to create a weathered and worn look, then run Distress Ink (Walnut stain) over the paper lightly to add depth and color. How cool is that.
Supplies I used were: CTMH cardstock and B&T Papers (Simple Pleasures), Stamp set: (Make it Count)
