In case you can't see it , I took a cardboard box, a little heavier than a gift box but still pliable and ran it through the bigshot with a cuttle bug file. I only did 1/2 of the chipboard with the design and it did leave a little indention that covers up, you can do the entire piece.
Rounded my corners, punched holes, distressed with Desert Sand, added some corkboard and there you have it! Yes you can still sand it!
Make your pieces any size you like, leave them square or round the edges. Use piece for a card front, album page, layouts or whatever you like. If you have dies you can cut flowers, ABC's and more from your chipboard, pretty neat! Then just distress or sand just like grungeboard!
Add glimmer mist, buttons, flowers or whatever you like for your project.
If you are using a thinner chipboard, do one piece and adhere it to another if you want it thicker. Set weight on it until firm.
