This little needlepointed T is on a hankerchief I got recently at an auction.  This is a close up but I can't tell you how tiny these stiches are.  Imagine this letter in the corner of a hankie and how could anyone do such tiny stiches in different colors.   It blew my mind.  I used to do counted cross stitch but would never tackle anything this tiny.  Awesome.  Following are more samples of hankies found at thsi sale.
