Corrugated Cardboard 12x12"

I used corrugated cardboard on many of my projects. Both to be seen and hidden as a 'filler'. 

I'm excited to be able to provide for sale corrugated card in 12x12" (approx). 

How or why do I want corrugated cardboard???
Cut it up and use it behind paper/things as a cheap alternative instead of foam tape.
Rip it and use on your project for a distressed look.
Cut it and use on your project for a 'warehouse' look.
Ink it and use on your projects.
Paint it an use on your projects.
Use it as a stencil.

The options are endless. It really is so versatile.
