Here's the pillow, but I also wanted to show you how to close up the opening on the bottom with an invisible stitch.
Here is the opening on the bottom of the pillow...pinned along the way.
Take your needle with a single knotted thread and bring the thread through towards you, so the knot is on the inside of the layer closest to you. Seen here in the picture below.
Now take your needle and bring it through the fabric right across from where the thread is coming out on the other side. (I hope this makes sense..hard to explain in written form)
Keep the needle inside the fabric under the fold for about 1/4" to 1/2" and then poke it out a little from the fold. See the tip of the needle coming out?
Now bring the point of the needle towards you and grab a little bit of fabric from the fold of the other side closest to you.
Pull snug. Now you do the same thing again.
Place the needle across from where the thread is coming out, travel under the fold and come out towards you and grab a little fabric from the other fold.
It's an invisible stitch, because the stitch that keeps the fabric closed together is under the folded part of the 2 edges of fabric.
