To Block or Not To Block?

I will preface this by saying I’ve never blocked anything before. I’m just about finished a Column of Leaves scarf done in KP Andean Silk(55% superfine alpaka, 23% silk, 22% merino wool) and I was wondering what would be the best method of blocking it or should I block it at all. :?? :shrug: I would appreciate any help I can get. Thanks in advance.

I have the same question, but about 70% mohair, 25% nylon, 5% wool.

Should I block? If so, how?
