Happy Memorial Day!
On Facebook, I saw a fellow mixed media artist using these letter trays as holders for collage papers. I loved the concept so I picked up a couple at Target for $4.99 each.
I find it much easier to sort through, and find, ephemera than looking in paper folders or envelopes. Most of my ephemera is stored in folders. I may purchase a few more of these trays.
Since the trays are covered in paper, I protected them with an acrylic spray to make them more sturdy.
