I always trim my threads to make my work as tidy as possilbe. I was the same way with my knitting, cross stitch, etc.
Ladies from the old country always made it a point to descreetly or not so discreetly turn the work over to check the back to make sure it looked as good as the front!!! Yikes! That's a lot of pressure for "perfection" to put on one's work!
I clip my threads because I am hardwired to be a neatnick...it's in my genes! :lol: :lol:
