Vintage Smocking Patterns

Two weeks ago, I hosted a family get together with my sisters, spouses, a sister-in-law and a few nieces. I mentioned to my oldest sister that I wanted to make a smocked dress for my newest granddaughter whose due in December.  (This sister is an amazing seamstress and has sewn for probably 60 plus years.) I asked her if she had a pattern or tips for hand smocking and she said she had a few patterns she'd send to me. The next week, in the mail, look what arrived!

Pretty great having a sister like that, don't you think? Luckily, the pattern pieces were in great shape. I've made copies so I don't ruin her originals. It looks like the top pattern will be my next project.

Has anyone done any hand smocking?  
Does anyone have any tips you'd like to pass along to this novice?
