Pick the rose petals and make sure they are free of dew. Half fill the net bag and close with an elastic. Hang the bag in a warm, dry and dark place to dry. This will take anywhere from a few days to a week, depending on the humidity of your environment. You can also spread petals out on top of a paper towel on a tray or large dish. Keep them in a dry area that has good air circulation.
If wished, small dried rosebuds can be included for appearance. Ensure that these are organic too.
