It's easy to misplace a CD or DVD case. However, instead of buying another one immediately, you can make a small paper envelope for the disc in no time. It won't take you more than a minute to create it, and once you know how it's done, you'll want many more.
Steps
Method 1 of 2: Make a Traditional Envelope

Step 1. Place a CD or DVD on top of the paper
Place a piece of paper in front of you in an upright position (portrait type), that is, with the shorter sides at the top and bottom. Then put the CD or DVD on top. Since the paper is in a vertical position, the top will be shorter. Then align it with the top of the puck.
This step will determine the size of the envelope

Step 2. Fold the vertical sides inward
Keeping the disc in place, fold the right vertical side of the paper towards the center of the disc and then do the same with the left side. Fold the paper as if you were going to wrap the disk with it.
Note that the folds will not cover the entire disc

Step 3. Remove the disc and fold up the vertical edges
Take the disc out making sure not to damage the folds. Fold the edges so they are flat and sharp once you've removed the disc. The paper should hold its shape on its own.

Step 4. Place the disc in the center of the paper and fold the bottom side up
Put the disc back on top of the paper so that it fits into the folds. Fold the bottom horizontal edge up toward the disc in the center. The top of this fold should extend just above the center hole in the disc. Remove this after folding.
Fold the fold with your thumb, making the edge flat and defined

Step 5. Pull out the inner edges of the bottom crease
Turn the paper so that the fold you just made is farthest from you, and fold it up. Scoop out the inside edges so the fold looks like an arrow. The remaining parts of the paper on the sides are the "ears."

Step 6. Fold the ears around the vertical edges
Hold the ears you just created and fold them along the vertical edge back to their original position. You should see a pocket of paper when you fold both ears.

Step 7. Fold the top corners of the envelope inward, and then insert the disc
Turn the paper so that the unfolded side is away from you. Fold the top corners inward. However, keep in mind that these corners should not reach the inside folds of the envelope. Finally, put the disk in the pocket you created earlier.

Step 8. Fold the top of the envelope down and put it in your pocket
Fold the top of the envelope down, keeping in mind that the two corners you created previously will function as hooks. Also fold them into the pocket above the record.
You can use a marker to label the other side of the envelope with the information on the disc
Method 2 of 2: Make a Letter Envelope Fold

Step 1. Lay the paper on a flat surface and fold the top left side down
Lay the paper flat on a table, meaning one of the long sides should be close to you. Take the upper left corner of the paper and fold it down toward the bottom edge, about 2 inches (5 cm) from the lower right corner. This will be the first edge.
Run your thumb along the folded edge to flatten it

Step 2. Fold the top right edge towards the horizontal edge of the first fold
Take the upper right corner of the paper and fold it inward so that it contacts the vertical edge of the first fold.
Now the top of the paper will resemble a pyramid. This will be the second fold

Step 3. Unfold the first fold and turn the paper 90 degrees counterclockwise
Open the first fold and you will see a long crease in the middle of the paper. Rotate it 90 degrees counterclockwise so the short edge is facing you.

Step 4. Take the upper right corner and fold it
Fold the top right corner of the paper to the center. The top edge of this fold will line up perfectly with the second fold. Next, use your thumb to flatten the crease. This will be the third fold.

Step 5. Refold the first fold, and then flip the paper over
Keep the paper in the same position and do the first double again. This will return to its previous position due to the pre-existing crease.
Once you have flattened all the folds, turn the paper over so that the flat edge of the first is closest to you

Step 6. Fold the remaining small triangle inward and reorient the paper
Now there will be a small unfolded triangle. Fold it towards the back of the paper, creating the fourth fold. Then reorient the paper 90 degrees counterclockwise so the short side is closer to you.

Step 7. Fold the bottom of the paper up, stopping at the fourth fold
Remember the location of the bottom of the fourth fold. Take the bottom of the paper and fold it up so that the crease lines up with the bottom of the fourth fold. You will now have created a pocket with a small triangle pointing upwards.
Flatten all the edges so they are sharp and neat

Step 8. Put the disc in your pocket and fold the triangle down
Slide a puck into the fold of the paper making sure it fits snugly. Then fold the triangle at the bottom of the envelope down over the puck. This will keep it in place.
