Infant heirloom? Day gown/saque? Formal dress?

Starting out with one of the "I don't even know what that is?!" classes. 

Infant clothing. Figured that's gotta be an easy place to start- they're just tiny little things, their garments are small and should be quick to make, right?

Not quite.

I started by googling the class descriptions because I couldn't tell you the difference between a day gown and a play outfit even if my life depended on it. Unfortunately, that didn't help much. They all look the same to me..

Im not one to let cluelessness stand in my way though, so I started working. Reckon I'll figure out just what it is I'm making somewhere down the line.

Pin tucks- I knew that my machine could do 'em, but I'd never tried it this way before. I dig how they came out and how relatively easy they were.
