My son had been asking me for awhile to make him the red Koopa with wings; Koopa Paratroopa. I finally got some time to make him and he turn out perfect. The pattern I use for the Koopa was a free pattern courtesy of Lupita Suarez; link to pattern. I just change the parts that where green to red. It's a very well written pattern. :) For the wings I use Melissa Mall pattern; The Golden Snitch.
I use a 4.5mm hook for the wings and it turn out to be a perfect size
for the Koopa. I love the way it turn out and so does my son. :)
