Transfer to your fabric and cut out all pieces.

Remember to leave half an inch or so as seam allowance!

Now start with sewing the inner seam of the cheeks - no need to sew on the outer part, you'll take care of that when sewing front and back side together.
Fold the fabric along the marked line and tuck the seam allowance under. Use pins to hold in place or iron it flat. Pin it onto the head piece (right sides up, it's like an application) and sew very close to the fold with a simple straight stitch.
Do that for both cheeks.

Now is the perfect time to arrange all the smaller black pieces on the front piece of the fox head until you are comfortable with the look. For such tiny pieces I recommend to stitch them on by hand. For the ear tips and the nose you don't need to stitch on the outer edges.

When all pieces are stitched onto the front head piece, turn it around and cut off the overlaying fabric.
Take the two main pieces (right sides together) and sew them together leaving 2-3 inch open.

Pull everything through the remaining hole so you have the right sides outside.
Stuff the Little Fox Rattle with polyester stuffing and add the rattle insert in the middle of the fox head.
Sew the opening close by hand.
