I finished my first hat over the weekend. Took me a while to get the double decrease I was doing right, so there's a zig zag in the decreases across the crown. I decided to leave the wrong ones -- the zig-zag looks deliberate. Also, while I did a gauge sample and based the size on the sample, I didn't know how much to reduce the size to allow for stretch, so I didn't, which means the hat really is a bit on the big side, since unstretched it's just the size of my head. Might be better for someone with dreds. On the other hand, it is an object, it is finished, and it looks pretty good for beginner's work, so I am provisionally pleased. But I still have a bit of yarn left over so the question is: tassel or not?
