That waxed dental floss sewn along lines with a basting stitch can be pulled tight for water, that waxing a fish into plain cotton with a mixture of paraffin and beeswax, then dipping the cotton in blue dye gives you a memory of watching coho spawn in the creek near your house, a cycle that has been going on since the last ice age at least. That others have dipped cloth into dye and worn the pigment on their hands for weeks afterwards.
