Save all your onion skins in the freezer until you have sufficient. Bring about 2 L of water to the boil and put the onion skins into the water. Once this has cooled, it can be put into a bucket and left in a warm spot for a week. Strain off the liquid and add some liquid soap and spray plants to prevent aphid attacks. Bury the bits of onion skin around the plants.
