yes, they are quilted. They're each about the size of a fat quarter. That's what they're backed with. They are backed with inexpensive "what was I thinking when I bought this" fat quarters ;-)
I quilted aprox a 1.5" grid. I work on these when I'm between projects or don't know what to make next. They are my threapy quilts ;-) Sometimes I just sew aimlessly when I'm in a funk. Like going for a drive and not knowing where you'll end up.
