In our group we had to create our own digipack and to begin the process we had to clearly map out how we wanted it to look like.
This is our hand drawn digipack mock up:
We labelled the key conventional features on our digipack that included the band name, album title, spine, image, record label, copyright information and bar code. From doing this, it made it easier for us for the digital mock up as we knew roughly how we wanted it to look like.
