Making hats is a god way to try new stitches in nalbinding. The stitch used this time is often called "Dalby". I found a good description of it in the book "Gamla textila tekniker i ull" by Kerstin Gustafsson. It is described in a chapter called "Nålbindning efter Maj" (Nalbinding according to Maj). The stitch is common in the Dalby-area in the north of Värmland, Sweden.
The yarn used is a loosely spun single in 100 % wool, "Samo" from Marks & Kattens. I found it a little too loose, but I got used to it. This finished result is OK and dense enough to be warm and cosy.
I made the hat "long" enough so that one can fold the bottom part of it into a cuff, to get more warmth.
When it was finished I dyed it brown, and I am very pleased with the result. I found the Dalby stitch easy to execute. Done with a thinner yarn it would probably also make excellent mittens.
