I'm a big fan of blocking things. It's a fantastic way to line up stitches, hide away little mistakes, and get all that grime from knitting off your knitting. In fact, one of my favorite things when blocking something is seeing all the colors change in the water. I know that's weird because it means the dye is bleeding out, but it makes me feel like it's finally done. I also like seeing how the yarn blooms after it's washed out.
I'm always amazed by people who don't block, I don't understand that... When you wash your stuff, don't you lay it out the way you want it to look when you wear or use it? Isn't that blocking? I think a lot of people are under the assumption that blocking requires pins, wires, or other random things to make it work. For everything I've knit, all I have used is a towel and some Woolite.
I really enjoyed this tutorial. I think the idea of maintaining the shape of what you're knitting while it's wet is so smart, yet something that had never occurred to me. I'm definitely going to try it out next time. The only thing that seems to be missing is that she doesn't discuss what kind of wash she uses for it.
