I never realized the pith was so... pithy.

This seems like a good application for a tilt/shift adapter.

It hurts my head to think about tilt/shift (which I hadn't heard of before).

Would such a tool be useful for avoiding keystoning when I take a photo of a large quilt? Usually I lay the quilt out in the driveway and lean way out my window, but I still can't get the camera over the center of the quilt.

Yes, the shift movement will let you eliminate keystoning, and the tilt movement would let you put the plane of the grapefruit into focus even if it's not aligned with the plane of the camera.

Search for "shift" in this article (http://photo.net/learn/architectural/exterior) for a striking comparison, or read this one for simple illustrations (http://photo.net/equipment/canon/tilt-shift). It's surprisingly difficult to find clear illustrations of what tilt is good for right now, but some good triptychs in this one (https://luminous-landscape.com/focusing-tilt-shift-lenses/).
