As promised, here is a photo of my hat on the blocking board:
I'm trying to enforce a boxier shape on top, while keeping the band snug. A few of you left some blocking questions in my comments earlier this week. I always wet block my wool things. A ten-minute soak in a warm-ish water (just because it's nicer on my hands if the water is not icy) to which I have added some wool wash or (if I think that the yarn might need a stronger soap) dish detergent. My current brand is Dawn, but I don't think that the brand matters. Maybe I swish the knit around in the water (gently, no felting needed here), maybe I don't.
The drawback to dish detergent is that it must be rinsed. If I rinse, I drain the sink, squeeze out as much of the water as possible, and then refill the sink with cold water. I make sure that the stream of water does not run onto the yarn to prevent felting. I let the knit soak for about ten minutes. Again, maybe I swish it around the sink, maybe I don't.
There's not much to it. When I'm satisfied that the yarn is rinsed, I once again squeeze out as much moisture as possible. Then, I lay out the knit on my blocking board t0 let it dry.
I don't find that my knits block smaller (as someone asked). If anything they bloom and stretch.
