Here's the shift gaiter pattern for you...
Here's how everything fits together.
Since I dyed it, it's really easy to see where the seams are.
Depending on how easy it is to scale your printer,
you may just be able to print this out full-size and have an instant pattern...
If not, here's a "tailor's draft" of the patterns so you can draw it up.
