2. Label each piece with the name of each pre-wash stain remover and the stain

3. Measure 5ml of Vegetable Oil and pour onto center of a cloth

4. Use an eyeliner pencil and draw a 3cm diameter circle with a compass, on another cloth

5. Squirt a 2cm line of tomato sauce on the third cloth and smudge it in with fingers, making sure everything stays on cloth

6. Pour 5ml of Black Coffee (http://www.wikihow.com/Make-Instant-Coffee) onto the 4th cloth

7. Repeat steps three to six, 4 more times. There should now be 5 of each stain, totaling to 20 cloths all together.
