i made these for my bands demos, they are really easy, fast and something a bit special!
i used old picture books but you can use any thing like
-recycle gift wrap
any thing, go crazy
make this to the dimentions (you will need a peice of paper at least 15CM by 27Cm), then cut out!
fold over the flap bits then fold in half, and glue.
its that easy!
i made heaps for all my odd mix cds, now they are never damaged form laying around my house.
