Take your four pieces of knit and sew them all together, making a bowl type shape. Start with your hat and the lining inside out. Put the two together and pin, matching at the seam. Sew around the edge, leaving a space big enough to turn it. Turn it right side out and try it on. You may need to make adjustments to the lining so it fits nicely inside the hat.
Turn right side out when finished. You can stuff the tail with a bit of stuffing, I think it makes it look fuller and rounder, giving it a nice shape. Don't forget to stitch up the hole!
Now, all that's left is to go enjoy your hat!!
