Use only scraps for your project - (card base or similiar "base" ok to use new) but use some of the scraps- paper, ribbons, the odd sinlge embellishment, etc OR recycle something- redo a former card, use something that was intended for a different purpose- ribbon from a package, coffee cup sleeve, corrugated paper, button from a shirt, etc. Be sure to note in your post how your entry fits the challenge!*
*Both cards fit the 'scrap only' challenge - no full pieces of paper were cut into, parts were either existing or from larger pieces of scrap, ribbons were in 'ribbon bit pile'
**Whenever I cut into a 'virginal' piece of cardstock, and leave more than half a page, I cut a 4.25"x5.5" piece and put it in my 'card base pile'.
