First, cut out all the pattern pieces. Then, layout the colored felt and pin the pattern pieces to the felt, then cut them all out. I did not include the round circle for the head of the red Angry Bird - because I traced a dinner plate to make my circle. Then, I trimmed the circle down to a size I thought looked nice. I recommend you do the same. Also, I forgot to add the four round circles (two large and two small) to the pattern - for the red spots on the birds cheeks - you can cut these out free-hand if you would like the bird to have them.
Next, make sure your blanket fleece is trimmed and cut to the size you desire. Then locate the area where you plan to sew on the Angry Bird - and mark it with chalk. Layout all the pieces you cut onto that spot, so you can make any changes or move onto sewing.*If you're making your red Angry Bird on fleece that is also red, then I recommend that you cut out one additional circle in white (either fleece or felt is fine) - and make sure the white circle is about a 1/2 inch bigger than the red one. Then trace and cutout your main red circle in felt or fleece. The reason I did this is to show some contrast in the colors - and the blanket looks nicer this way. Then sew the red circle onto the white one.*Tips for Sewing:
If you have a "fancy" sewing machine, and you are comfortable using a different stitch, something similar to the "blanket stitch" - and you have the time & patience to do so, I recommend it as it looks better & holds the edges in nicely
Otherwise, it is fine to stitch with the standard sewing machine stitches
I don't recommend stitching all this by hand - as the material becomes very thick and it would be difficult
