You can mark the inside of your stove with a pencil and then scratch it in with a nail. Just hold the can steady and place the body of the nail on the side of the can and then turn the can, pressing the nail end to mark it around the inside of the can. This way you won't need any measuring cups.

I put a drop of food dye in my alcohol and works just fine. This way I know how much is in the stove, and alcohol container.

You can wrap the stove with a bandana or Handi wipe and place it in your cook pot. Both items are great for cleaning, as a cozy or hot pot holder...napkin..etc.

I tried the stove last night and it works great.
