The yourATCstore's Doors from Afar 2 collage sheet is the second collage sheet that was created from photos that I took when we were on our late cruise in March. The colorful doors are all different sizes for you to use when creating your ATCs, greeting cards, and other altered art projects. The first door measures 3 1/4 in. x 2 3/4 in. so you can get an idea of their different measurements. There are also 2 windows on this collage sheet. This matte finish collage sheet is professionally printed and comes in a crystal clear bag for protection. Sheet measures 8 1/2" X 11". Acid Free.
