Yesterday I had the question asked "How do I end my floss without it looking messy?"
I guess the definition of the term "messy" can vary by person, where one person can think it looks good and another will think it's not. Hence the saying "Beauty is in the eye of the beholder".
I'm sharing a picture of part of a piece I'm currently working on. For
the 35 years I've been stitching I've always ended (and started) my strand of floss
the same way, by running it under stitches that are close to it. I
always try to run it under stitches of the same color, but that's not
always possible, so I try to use a color that's as similar as possible.
Once I'm done completely stitching the piece I'll go along and trim up all the pieces that stick out from the threads, like the blue that is running through the tan, so there aren't any "tails" sticking out. I still do this even when I'm covering the back of the piece where someone won't be able to see the stitches.
Hopefully this clarifies the question and might teach someone a new technique. :)
