No one should be concerned that a Quirky B. they might like, nay, covet, won't fit in with their existent art or decor.
These boards are flexible and form artistic alliances with whatever else is on your wall.
You don't really have to worry.
And if you insist on being concerned, there is always the option of
commissioning a board in the colour or texture, size even, that you want.
See how easy it is to become a patron of the arts?
