Keep clothes warm, Simply by putting the next day’s clothes in your sleeping bag while you sleep.
Toilet paper. Keep from being crushed or getting wet. Just take a plastic container i.e. pop bottle pop the roll in, and then cut a slit in the side to run the paper out of.
Stiff zippers. Put a keyring on them. This is especially useful if you’re camping in cold weather and are wearing gloves or mittens.
Firelighter’s, Coat a cotton ball in Vaseline and then wrap it in a square of aluminium foil. When it’s time to use it, cut an X in the foil, pull a bit of the cotton out, twist it into a wick, and light it. It should last about 10 minutes.
Boating or swimming, Attach your keys to a cork. practically essential .they could be hard to find
You’d be surprised how many campers don’t carry any first aid items.
Some rather than none a good idea.
