There are several different ways to store your scraps, but this is my method.
I make cards away from home quite often, so I needed a space-saving way to store my scraps. Big sheets of paper (12×12 or 8.5×11) sheets get stored at home in hanging vertical file folders. This is my travel kit of scraps. I cut page protectors in half, and designated one for each color family (Red, Orange, Yellow, Blue, Green, Purple, Browns, Black/White) and I store them in a Rubbermaid box that I found at Walmart for $1.88! Teeny pieces go into snack-sized zip top bags in each page protector.
