Here is the basic concept for making a personalized CD case for your special someone.
Paper - cardboard, construction, or cereal boxes.
Scissors- Exacto Knife
Step 1: Applying Concept
So I used cardboard paper for my project and I decided to make my CD case hold four CDs. You can build bigger or smaller depending on your specifications. It wasn't too hard. I use an Exacto Knife to cut the slots. Then I measured with a ruler the length of the cut to ensure my flap could fit. For the extra flap, I measure the distance from one end to the other end. Every block square should be the same length and height. For the center fold I put extra folds. I put lines for help me out for this about 1/8" apart for each fold. The outer folds were just plain simple folds. I put extra work in the middle fold to make it more block like you would see on a regular album.
Step 2: Extra Aesthetics
You can put designs if you like on the back of the paper to make it look better. Unless you like it the way it is.
