Blocking Noro Silk Garden scarf

Eeek! Help! Never blocked before!

Terribly close to the deadline for shipping my ISE4 scarf, and I think it needs to be blocked.

The [U]pattern has a slip stitch on each side, but it’s curling in.

After doing some research, it sounds like a pin and spritz yarn?

Should I pin it on the side where I’d be pulling the curl back DOWN toward the surface it’s on? (concave side, vs convex)

Ack…this shouldn’t be this intimidating, but it is.

When I blocked my curling yarn. I placed the curling side down so that I could flatten it down. My right side was facing up (if that helps). I put it in water and pinned it on my ironing bored. I’m not sure if you can do this with your yarn, but I also placed a pillowcase over it and lightly pressed the iron on it and quickly picked it back up.
