I love the Scrapbook.com storage envelopes--I have them in every size available and use them to store my dies. I mount the dies on magnetic sheets backed by light wight cardboard or the paper they come with and then keep the envelopes in plastic containers. I sort dies by brand, special occasion [e.g. Christmas] or type depending on what makes them the most retrievable. The storage envelopes are very sturdy and see-through. They have transformed my die storage and provided a solution that is neat, convenient, and practical.
