If you intend to burn the album open source on a compact disc, here is all the necessary stuff to dress it up.

The artwork exists in two versions:
Regular version (using the colors of this website).
"Ink-conscious" version (on a white background).

Each version consists of two PDF files:
The booklet (to be folded in half); it can be inserted in front of the disc ("jewel" case, either regular or slim), or the disc can be inserted in it (plastic wallet).
The inlay, meant to be placed under the disc tray (standard jewel case only).

Regular version:  booklet + inlay
"Ink-conscious" version:  booklet + inlay
