Maybe-isms for triangles

As a child fond of triangles, I wanted to be able to manufacture triangle-shaped items, such as cups, shoes, etc. Now, I have access to the most triangle-like letters, which I have decided are:
AKMNVWXYZ

Maybe-isms for triangles:

A NAVY YAK MAY YANK MY WAY WAVY YAM.

A WAN MYNA MAY AX A WAX MAW.

ANY ZANY MAN MAY YAWN.
