I used to keep a Primas in their containers and recenty converted to this metod of using different 12x12 page protectors. I sorted by takeing each out of its container one at a time...then sorting each container by its colors. Then I put them in these page protectors...these ones are by Lisa Bearnson...adn I adore them because they are lots of diff. sizes! i sealed them with a piece of tape...because it takes me no longer to pul it off then to open a jar.
