I just took 4 blank cards and scanned them into an image file on the PC.
Dropped it into Word and drew text boxes on them.
Then I copy/paste the track lists from media player, twiddle with the font, paste in a band logo sometimes.
Made some pretty cool custom looking ones. Prints 4 per page.
Next I'd like to scan in the booklet covers along with the cards.
Make inserts on a single peice of heavy paper, easier to shuffle around, save wear and tear on the booklets, etc...
Worst part is cutting the holes for the CD number to peek through.
Wish I had a square drill for that.
Let me know if you'd like the DOC file.
