I missed your page when I was OOT this weekend, but below are the steps I took to make the envelope liners for my invites: I traced the flap of my envelope onto white paper, then came in .5" from each edge and drew a straight line. I scanned that in and took my photo into Photoshop and used the outline of the flap as a selection, deleting the inverse. You could also just add the outline to your photo, and cut along that line rather than deleting/cropping. I made sure the photo would extend 2-2.5" below the envelope edge, and printed all of them out. Cut along the edge, place .5" below the edge of your flap, and secure with a glue stick. I pressed them flat between two heavy books so that they wouldn't dry wrinkled from the glue stick. Hope that helps!
