I ran across this pattern from 1982 (is that vintage?) My mother made it for my daughter's first birthday. I have never done any smocking, but might be tempted if I ever have a granddaughter. My mother used to do lots of handwork (knitting, embroidery, smocking, etc.) which could be why I am drawn to such things. She never did teach me how to darn socks, though.
Here is a picture of Kate in the dress. She's still that cute :-)
