Tutorial: Ruby Slippers from “The Wizard of Oz”
Step 3: Tack the mesh onto the shoes

Put paper or fabric inside the shoes to help hold the “stretched” dimensions.

Tack the mesh over the entire shoe, securing the edges on the bottom.
Sew down the center back seam as flatly as possible.
WHY? I wanted to be able to see the placement of every sequin on the shoes in a 3D space, so I used a power mesh pre-stetched on the shoes.
