Here are some tips on how to save kindling wood:

Store it in a dry place: Moisture is the enemy of kindling wood, as damp wood can be difficult to ignite. Store your kindling wood in a dry place, such as a shed or garage, to keep it dry and ready to use.

Use a kindling box: A kindling box is a container that is specifically designed to store kindling wood. It keeps the kindling organized and prevents it from getting scattered around. You can even make your own kindling box using a wooden crate or box.

Gather kindling in advance: If you know you will be starting a fire later in the day, gather your kindling wood in advance. This will give the wood time to dry out and be ready to use when you need it.

Cut kindling into smaller pieces: If you have large pieces of kindling wood, consider cutting them into smaller pieces. This will not only make them easier to handle, but also allow you to use less wood to start a fire.

Use alternative kindling sources: If you're concerned about using up all your kindling wood, consider using alternative sources of kindling, such as dried leaves or twigs. Just make sure they are dry and flammable before using them to start a fire.
