Rosebride, I found that my HP scarf improved a lot after blocking. since it's a tube, blocking makes everything lie flat and straightens everything out. It makes it less bulky, too - as I was knitting it, I was unsure as to whether it'd really be practical to wear, since it's so thick and so bulky. But after blocking, the scarf lies, flat, is even, and drapes better. so that's my two cents.
Even though I was feeling lazy, I blocked it anyway. It's just about dry right now, and you're right, it does seem much flatter and less stiff. I never understood the magic that a bit of water can do, but I've become a believer!
P.S. Luv2stitch, those scarves are beautiful!
