When I was at the museum in Helsinki, I saw in person this amazing “basket” headdress made with trichinopoly (aka Viking Knit) in silver wire. It was stunning, and super unusual. I’ve seen a scant few Finnish Iron Age reenactors online have made their interpretation, and I decided that this HAD to be on my project wish-list.
Unfortunately, research available on this piece is even more scant than the reproductions. The museum offered very little information about the piece, so the bulk of what I know has been gathered from reenactors who live in Finland.
