Look at the cool little thing that I put together to hold our matches when we go camping!
I got the idea from this blog post, which I think is really cute but sort of impractical for camping because of the glass. We occasionally buy gum in these plastic containers that I realized would be perfect to repurpose for the job because it won't break, yet will keep the matches nice and dry. I added super fine sandpaper to both the outside and inside of the lid, so there's plenty of place to strike a flame.
