This is a very easy way to keep your caseless CDs/DVDs from scratching
All you need is a sheet of normal sized construction paper and the CD/DVD

Step 1:

Place the cd on top of the edge of the paper as shown. (Try to have half of it on the paper and half of it off)
Then, fold the bottom and top sides as shown, make sure you align everything correctly

Step 2:

Next fold the cd and the paper to the right. Making sure everything stays aligned.
After, fold the opposite side to the left crease well an unfold.

Step 3:

Now fold the corners towards the middle as shown.
Fold back to the left but this time insert the newly made point inside the slot. This will be your back, turn it around and decorate as you please.
