Tinko is a doll made entirely in one piece.  Yes, there’s a bit of sewing, but it’s nothing major.

Materials
Yarn and an appropriately sized hook.

I used:
– Red Heart Super Saver in Buff and Red (maybe cherry red, they’ve got a lot of reds)
– H hook

Instructions

Note that I first give the instructions plain, without any of the color work.  That way you can add your own without having to reinterpret things.  The instructions for the diaper/undies will be at the end.  Also, this is done in a spiral without joining, so you’ll probably want to mark the beginning of the round.

Edit as of 2-11-2011: Noticed a small missing instruction. I’ve marked it in blue.

Place a marker in the 4th sc from the hook
Place a marker in the 9th sc from previous marker

Hold doll head towards the floor so that the front of the doll is facing you. Attach yarn with a slip stitch to the sc directly before the marker that is facing you. The start of the round will be in the stitch directly after the marked sc on the side away from you.

Finishing

Step 1 – Remove markers. Poke some more stuffing into the body through the gap between the legs if needed and then stitch gap closed.
Step 2 – Gently stuff and then sew the seam on each arm.
Step 3 – Embroider face.
Step 4 – Take a length of your yarn and tie it tightly around the neck to define it a little better.
Step 5 – Deal with yarn ends.

Instructions for the undies shown in example
Note that these instructions REPLACE the rounds that they are labeled as. I found it easiest to strand the unused yarn through the stitches, but do what works best for you. I’ve color coded the instructions to make them slightly easier to follow.

R = Red
S = Skin tone

Rnd 16 – SC 2, Change to R, SC rest of round
Rnd 17 – SC
Rnd 18 – Sc 6 with R, sc 3 with S, sc 6 R, sc 3 with S
Rnd 19 – Sc 1 with S, sc 5 with R, sc 4 with S, sc 5 with R, sc 3 with S
Rnd 20 – Sc 3 with s, sc 1 with R, sc 8 with S, sc 1 with R, sc 5 with S

Note that the stitches I have you mark in the leg section are the only ones that are still red if you use the undies the way I have them written.
