Yes, it's
two rectangles that you make and join together (as Amy shows in the video).
I'm just about finished with my toddler poncho, but have an elementary question on finishing it. When I "sew" the two rectangles together, how, exactly, is that done? Do I just thread a yarn needle with the yarn and whipstitch the two edges together, or what?

This is only my third project, and my first two were scarves. I am totally clueless here.
