Our (high %) wool blankets don't require much care seeing as we are careful with them. Much like any gear item we don't kick them across the portage nor drag them thru the bog. Like our sleeping bags, the blankets may be hung out on a rope or bush from time to time if we want to air them. She likes to wrap herself in one in front of the fire on chilly nights under the stars otherwise they stay indoors in the tent. We don't go to bed smelling funky, otherwise those tent walls start to close in and you wake up thinking you've camped out in your teenagers' closet. Simple daily hygiene is easy even if the lake is too frigid for a swim. My wife does wash the blankets but that's infrequent and only when necessary. We have a wool setting on our washing machine; rinse, spin and hang to dry over a clothesline (no pegs) indoors or out depending on the season and weather.
Wool is worth "the effort". Wool is actually a fairly tough, durable, sustainable, natural fibre well suited to tripping. That's only my opinion.
