Hang the fresh herbs upside down on a clothesline with clothespins until the leaves of the herbs are completely dry. Take them down and set them on top of a plastic bag that has been spread flat.
Label your tin canisters with the names of the herbs. If you do not label your tins, you may get your herbs confused when you try to use them. A lot of herbs look the same when they are cut up.
Place plastic bags into the tin canisters as liners for the herbs. Sometimes dried herbs will absorb materials around them and if you do not use a liner in a metal tin canister, it can give the herbs a metallic taste.
Cut up the herbs, one herb at a time, and place it in the appropriate tin. Fold the plastic bag on top of the herb and make sure the tin canister is sealed tightly when you place the lid on.
Keep the tin canisters out of direct sunlight if they are transparent or translucent and you wish to keep them out on the counter. Otherwise, store in a dark cabinet or pantry.
