This is the interior of my tri-fold gift card holder. With a few alterations it could hold 3 gift cards. That's next on my list to try. :) Opened the holder measures 4" wide by 9" high.
When you open the holder, you have three panels. In the top panel, I used the matching line art image as a watermark and used one of the sentiments from the Coffee with Friends Sentiments set over it. The middle panel is where the gift card is attached. In the bottom panel, there is a pocket for a tag or card to write a message to the recipient. I used another of the pre-colored images from The Perfect Blend set as my card/tag front and matted it on kraft cardstock. This is a picture of the tag inside of the pocket.
