Whether you are facing a situation where you have to carry something heavy through a self-closing door or you have a high-traffic area that a constantly closing door is an inconvenience to, something as simple as a door stop can be quite useful. This creative design can be made without timber, a table saw or other more-expensive items.
Fold the cardboard across the shorter, 15 cm (6 inch) width side approximately 5 cm (2 inches) from the top. Flip the cardboard over and fold toward you lengthwise, like an accordian. Continue flipping and folding until you reach the end of the cardboard. You should have a fan-like piece of cardboard folded in 5 cm (2 inch) sections. If your door is higher than 5 cm (2 inches) from the floor or ground, you will need to use a wider piece of cardboard folded in wider sections.
Trim any excess cardboard. The excess is useful as a brush to spread the glue with later on.
Cut the cardboard along the creases, which results in six 5 by 15 cm (2 by 6 inch) cardboard strips. It does not need to be exact, and actually works better if it is not, as this increases friction and helps stop the door.
Cut each rectangle in half diagonally, from corner to corner. Again, it does not need to be exact.
Spread glue evenly and thinly on one of the triangle's face and glue it to another triangle, lining up their right angles. Press them together, but not hard enough to squish the inner workings of the cardboard. Continue this step until all the cardboard triangles have been glued together.
If the doorstop slides too much, place some dots or lines of hot glue on the underside to give it a better grip on the floor. If you don't have time to wait for it to dry, use hot glue, which will also make your doorstop more durable.
