Step 1: Materials
-White piece of paper
Step 2: Cut the Wax Paper to Size
Step 3: Tape It All Down
Now once the wax paper is sized correctly, pull it tight across the top of the paper, and tape down each side of the wax paper. If there are any wrinkles or loose parts, it will start to rip after a bit of use.
If you mess up, simply lift up the tape carefully, as the wax paper will not rip when the tape is removed.
Step 4: Enjoy Your New Mousepad!
I've found that this mouse pad works pretty well. So enjoy.
If you want a mouse pad bigger than one sheet of paper (I didn't because my mouse is super-sensitive, even when the sensitivity is turned all the way down), simply lay down another sheet of paper (don't overlap it, as that will make an uneven surface that will eventually rip), and lay some wax paper down over it.
After a lot of use, this pad may need replacing, as it is just wax paper on the surface. But it obviously won't take too long to make again.
Also, I got the idea of using wax paper as a mouse pad surface from here.
