Step 4: Make a dragon tail

Picture of Make a dragon tail

Using a side piece from the body of the sweater, I cut a diagonal line across.  I loosely measured how many inches between my son's behind and the floor. This is how I decided on the tail-length.

I cut more of those fins, gradually going smaller as I got closer to the end of the tail.

I tucked the fins inside and pinned where my seam would be.  I stitched it on my machine, turned it right-side-out, then used poly-fil to stuff it.  Looks great!
