Crazy Handkerchiefs I Love

 I really love handkerchiefs with strong geometric designs. Here are some from my collection with circles, squares, lines and such.

 Cogs?

 This hanky had a paper pinned to it, showing it was likely from a handkerchief exchange.

 This one give me vertigo!

The next two handkerchiefs are by Erin O'Dell, a midcentury designer.

 Faith Austin did this unusual handkerchief, very unlike her typical designs.

 Ann McCann was another mid-century designer.
