I need your helping fishing fans.

My son forever wants to dip a line when we're hiking but I really don't want to be lugging our rods and tackle everywhere I do love fresh fish - and fishing with my kiddo - though, so we're building a couple of pocket kits. The intention is to use the containers as both storage and for reels. Both kits have line, hooks, leaders, sinkers and some plastic bait. We'd like to work bobbers in too but are planning to use natural or found materials for now.

Has anyone else made one of these kits? any tips or tricks?
