If you're ever in Norway:http://fartoyvern.no/en/for-our-guests/about-hardanger-maritime-museum
The Hardanger Maritime Museum is awesome and you can learn about rope making, watch it being made and even make some yourself.
There's plenty of other maritime-related stuff (boat building, restoring and even a smithy) and a lot of the stuff on 'display' is actually being made/restored so you can talk to the people about the project they're working on. Don't miss the cafe upstairs with wonderfully delicious Norwegian cakes.
Travel tip - if you're in Norheimsund at the Hardanger Maritime Museum, check out nearby Steinsdalsfossen. At 20m high, it's a relatively small waterfall, but the most visited tourist site in Norway. Picturesque, too, if you're looking for a good picnic spot.
