I started with a test of my pattern out of felt. The shape already looked pretty good here, though I decided to make the ears a little bigger.
Whenever I refer to yarn wefts, this is how I make them. I cut my yarn into many short segements and sew them along to a central strand. His sprite in the game uses two colors, a purple and a light blue, for shading, so to mimic this style I alternated between two colors of yarn and mixed them in a semi random way. Once the weft has been adjusted a little, you can't see the thread or central yarn base anymore.
I also made shorter wefts of a mix of orange yarn using the same technique.
I sewed the ears first and added the orange fur for a little fluff and texture inside. When attaching the front of the face to the back I added purple yarn to the seam that rings the head. I don't think this is needed in the future, on later dolls I just waited until the head was completely sewn to then hand-stitch the wefts on top. It's considerably easier and doesn't make much of a visual difference.
Next I filled in the back of the head with wefts.
The stretch of the fur fabric I used made the snout stick out far too long, but some thread sculpting helped a lot in pulling the eye sockets and nose farther backward.
I knew that I wanted his button eye to be an actual button, and searched one out specifically. His other facial features are done with a mix of aplique felt and embroidery.
Finished face:
I must call attention to the little bugle beads as claws. That's the only interesting thing about the paws (they're sewn to the pattern and thread sculpted) but I love it.
The front arms are sewn into the seams at the sides of the body, while the head and back limbs are ladder stiched in place afterward.
His coat has a mock tweed outer fabric and a felt lining, I sewed it at the lapels and collar before turning it the correct way. In the future, I would leave the collar open and sew the bottom closed first instead, since the collar isn't visible under the yarn wefts.
I wanted it to have real clasps, so I used a simple loop and button design. Although not in his official sprite, he's often interpreted to have patches on his coat, so I added some stray patches and visible mended areas using orange and black to stay within the palette.
