A couple cheap things i like to do.
Ziploc freezer 1qt bags keep things handy and dry in my pack. I keep hand warmers and a 1/2 dozen nitrile gloves in one, toilet paper in another, and one with a bunch of extra bags just in case, for my fone, snacks or fire starters or whatever. They pack down small and things dont get lost or wear against other stuff, in those bags.
If i do need fire starters i keep the TP tubes and pack them full of dryer lint then fold or staple the ends closed. (Potatoe chips also work great as fire starters but are noisier)
For target practice at the range(or where ever) i make targets from cheap paper plates and just draw a quarter size spot in the middle, with a Sharpie marker. Much cheaper then those nice splatter targets. Altho some times I’ll find some nice targets left by previous shooters that only hit them once or twice and just left them posted(thx).
