Step 2: Body
Use the pattern to cut out all the various shapes from fleece, according to the colors and number of pieces needed as indicated on the pattern.
Sew the white belly piece to one of the orange body pieces. I did mine on the machine with a zig-zag stitch, although now that the doll is finished I wish I had sewn it on by hand so it matched all the other exterior stitching on the doll.
With the white belly facing in, sew the two body pieces together along the longer sides only.
Sew the round orange bottom piece into the bigger end of the body section.
Turn the completed body right-side-out, and fill it with polyester stuffing, leaving the stuffing about 1/2" from the top. Hand stitch the top of the body closed as shown in the last photo.
I filled my Hobbes doll pretty firmly with stuffing, figuring it would break down and become more floppy over time. However firmly you choose to fill your doll, just make sure you do it consistently in all the different body parts. I didn't do it on anything but the tail, but you could add stuffing beads to the ends of various body parts to add weight if desired.
As far as seam allowances, I usually just line my material up with the right edge of the presser foot on my machine, which I'm guessing is about 1/4".
