Luckily, I found the proper color tile for a years-later kitchen backsplash extension! (Lesson learned, don't tile just behind your cooktop; do the whole thing in the first place!).

Currently, this tile now is available only in a running bond pattern on backing paper, but I really want herringbone! Partly because I like it, but more practically as a textural change for the extension section so it fits better visually, since there is a slight size difference (1/8") between the old and new tiles that needs to be "masked."

Here is some detail from the manufacturer website -- this is not my color, but this is just to show the current tile arrangement and size as I would purchase it:

7/8" x 1 3/8"
Offset Joint

Collection Name: Muse

Item Description: 7/8” x 1 3/8” 30% Offset

Sheet Size: 11 1/8” x 11 1/8”

Thickness: .25”

For a larger tile, we could install it manually in herringbone, but for sanity, that's not practical for mosiac tile like this. Does anyone know of a mechanical way to convert this size of tile to the herringbone arrangement on sheets for ready installation? Thanks!
