Okay, so we're stretched, brushed with pink stuff, and stitched. Now its time to apply these "finishing tapes" which are just long bands of fabric with pinked edges. These will protect the rib stitches, and will also cover any part of the fabric that needs to be reinforced. This includes all ribs, edges, corners, etc. Anywhere that the fabric meets a hard spot. That Y-shaped piece in the middle is actually just regular fabric that I cut to the shape I needed.
