How to bleach pine cones

In this project, bleach comes in handy for something other than whitening clothes and disinfecting counter tops. Pine cones take on a silvery sheen after being bleached, which looks lovely set against a dark red, blue, green, or black table runner. The tutorial uses a 4-to-1 ratio of water to bleach, so if the water does not cover the pine cones, double the ratio to 8-to-2.
As this project does use bleach, there are several safety precautions required. Always wear disposable gloves when handling bleach and when the pine cones are wet with it. Pour the bleach slowly so it doesn't splash; as an added precaution, wear safety glasses. Ventilate the area in which you are working, and do not place the project where children or pets can reach. Keep the area ventilated while the pine cones soak.
