To make rosewater at home, boil rose petals in water and let them sit till the water cools down. Strain out the petals and the water left behind will be your rosewater. Melt the wax in a double boiler till it completely melts. Once it melts, put it on a slow heat. At this point slowly keep adding the rosewater and stirring the mixture. Once this is totally mixed, add the almond oil and stir it. Let the mixture cool down a bit till it turns warm. Pour it in a glass jar and store it in a cool place.
