Turned it into this:
And then this:

I've worn it two days in a row now, so I guess I like it. It's not perfect, but really, who needs perfection when pretty darn good is FREE? I drew a little pattern for the shape that I wanted on the neck and then cut it out of a men's white t. Then I added trim (also cut from the men's t), buttons and eyelet ruffles to it, and sewed it onto the shirt. Then I added more of the trim around the neck to finish it. The neck is the only wonkey part, and I may see if I can smooth out a few of those spots one way or another. But if not, I'm happy.
This is my fourth shirt for Spring Top Week. The fifth and final shirt is in the works. And I'm excited.
