Glue paper mats to front sides of envelope. You will not be putting any paper on the middle envelope on this side.
Glue paper mats to inside of album. Printed paper with notches on sides, solid cardstock with fold in middle. When gluing side pieces apply the glue to the envelope instead of the paper, and only to the top layer of the envelope, making sure you don't glue the "pockets" shut.
Cut other half down to 1 inch, glue to outside of back page as shown. Do not glue front triangle/flap down.
(Sorry, picture is sideways!)
