Cardstock. It is the staple of scrapbooking. It's a work horse: backgrounds, borders, mats, diecuts, journaling blocks, florals, stampable, embossable, glittered, textured, smooth. And we have stacks of it; measured in inches. Or racks. ;)
Today, create your layout, card or home decor piece using only cardstock. Cut it, tear it, punch it, stamp it. Whatever it takes to use your stash and be creative.
