Elastic Apple Watch Band Series 4 3 2 1 / Fitbit Blaze Bow Tie

Take a thin piece of string or dental floss.  Wrap it around your wrist one time.  Where the end meet precisely, cut or mark the string.  Then lay the string on a reliable ruler - this is your true wrist size and this is the measurement you will need to select.  Since these bands are custom made to order, there are no returns.  Apple watch device is not included.
