Fleece quilt- triangles

I made this quilt from scraps of fleece that were laying around.  The triangles are cut with a 60* triangle ruler.  It went together really fast (the fleece was surprisingly easy to work with on my Pfaff sewing machine), and it's super soft & warm.  

Since the fleece has quite a bit of stretch & thickness, it can't be quilted on the longarm.  I am planning on backing it with flannel, and the doing a tacking "X" stitch on my sewing machine in the middle of each triangle to hold all the layers together.  Kind of like tying, but I don't want the loose yarn ends that happen with that method.  

The quilt is about 57" x 69".
