Are you doing this yourself ? The Tile Shop should have some but layoing the patteren is real work and you need a really good tile saw too 3 x16 " is a good size for floor but you do not say where it is going.

How to do a chevron pattern with tile?To achieve a chevron pattern, each individual tile has to be cut at a 45-degree angle at each end. When being laid, the edges of the 45-degree angles will create a crisp V shape and zigzag pattern. The chevron design has only recently been used to bring life back into people's homes, due to its quirky appeal.

@Patricia Colwell Consulting Oh, that sounds like a lot of work. I was hoping to just buy parallelogram pieces or a mosaic like this https://www.ceratec.com/en/rss-1440-chevron-1786 but in the US.

A skilled tiler will be doing it.

Daltile Starcastle has a beautiful white stained glass chevron. https://www.daltile.com/products/mosaic/starcastle/milky-way

Go to a dedicated tile store, pick a white or whatever, take samples home, and make sure you like your selection with YOUR counter tops and cabinetry.

Or?? Tile bar!

Get the quantity you need from the"pro" who will install.

Last? Post YOUR kitchen in jpegs and not a screen shot of a miscellaneous someone.

THis pic you posted is IMO the pic to show what not to do the counters has graining quite dominant and adding chevron to the wall is too busy.
