So I'm new to sewing (got a sewing machine for Christmas!). I thought I would try my hand at something fairly easy like a baby's blanket. I have my two panels and some batting/wadding to go in between.

Now I am wondering, do I sew the panels together inside out and leave an opening to turn it out and then stuff the batting in? And then sew a decorative stitch around the edges to secure the batting?

Or do I sew all three layers together with the panels facing the correct way out?
