Blocking?

I finished one Fetching (weeeee!) but I think I should block it before sending the pair off as Christmas gifts. The top and bottom edge are curling slightly over each other. Not really a big deal, as they don’t do it when they’re on the hand. However, to look nice when not on the hand, I’d like to block it.

Problem is…I don’t know how. Can anyone help?

Here is a site that helped me regarding blocking. It’s long but the author has a good sense of humor. It does tell you how to block and how to make a blocking board if you need one. For small FOs I use my ironing board.
