Made my babes this dress tonight! from this tutorial (and free pattern) http://www.thetraintocrazy.com/2010/07/go-to-dress-pattern.html
I'm liking how it turned out, a bit plain but it'll make a perfect playdate dress!
One change I made from the instructions was a loop and button close keyhole on the back so it will go over babes head easier and i did two rows of shirring instead of elastic. I find shirring so much easier than making a casing and pulling elastic through.
