These are a few examples of the different panel designs you can use for a digipak. I found these on a really great website, which makes all of the digipaks from 100% Green Forestry Practices Certified board stock and high-quality vegetable based ink on both the boards and the discs. What I really love about these digipaks in particular is the custom designs people have ordered. I especially like this one:
I really like the unique idea of the middle panel having a pocket in it for a small booklet. This would be great for a booklet featuring the lyrics of the songs, which you often see with albums. I would also like to use a 6 panel digipak as there is more opportunity for adding different features such as a list of tracks, the lyric booklet, disc tray and plenty of images. I'm really excited about creating a digipak and can't wait to decide what I would like the end result to look like!
