Design your own Icelandic Monster, Skrimli at the original creator's workshop. The owner is a local who invented the Skrimli Characters and even wrote a book about the characters. You get to see parts of Reykjavik that are truly off the tourist path and spend time with a local one-on-one. She only takes private groups.
This is the best souvenior you could take home from Iceland!
You pick out all your fabrics and special add ons, like a tail, legs, hair, horns, whatever you want! Then the owner sews it up super speedy for you and you get to stuff it and design his face.
10/10 local experience, great for ALL ages!
