Blocking is wetting/steaming/stretching it to get to the finished size. It evens out the pattern, too. Not all fabrics need to be blocked. If it's acrylic, I wouldn't bother. Wool can be blocked, lace should be blocked to get the pattern looking the way it should. I block my wool sweaters to get them to the proper size, but I don't block the kids' sweaters that are made with a blend.
Lay the scarf out. If the sides look wavy or uneven, then wet it and stretch it out on a flat surface and shape it to the size you want. It's just like when you wash a store bought sweater that says to lay flat and shape to dry.

Thanks Ingrid! (I should just make that my signature, since I'm always thanking you for everything! :D )
It's 80% acrylic 20% wool, so i probably won't need to....but i might end up doing it anyway b/c it's my "hogwarts scarf" knit in the round and i kind of want the sides to be "creased" if that makes sense. I would rather it look like a dbl sided scarf instead of having rounded edges...What do you think?
