I used fleece the first time because I thought it would be faster than fooling around with 3 layers, and I was right. No fooling around to get the front and back to match with the batting between them. I just pinned them together (lots of pins like I mentioned before) and whirled away on the machine. If the fleece wound up a little crooked, it didn't make any difference, because it wa a solid color. I just trimmed it when the quilting was finished and bound it. If there's enough fleece left beyond the edge of the top, I use it as the binding, too. I slice off the corners of the fleece and miter the corners on the front. That does take a little work, but fleece is very forgiving. I use a blanket stitch on the front - pointed toward the fleece - to stitch the binding to the top.
