But, once you get it turned inside out and sew up the hole, do you then sew the whole thing together? Like, back, front, and batting all at once to hold it together?
I think that that would be considered the "quilting" part of the quilt- it would keep the batting and everything from shifting around, which would probably be a good idea if it's used for animals to sleep on. You probably wouldn't have to do anything fancy, maybe some diagonal lines or something (although you could do swirls, too!). I'm going to guess that for such a small quilt, you wouldn't need a quilting foot, but I'm not a "quilter" so I'm not 100% sure. Hope this helps!
