This pattern by With Thy Needle & Thread was much sought-after. I had to search several online sites as it was frequently sold out. The only specialty floss is whisper floss by Rainbow Gallery. This floss really brings out dimension to the beard. I modified the pattern a bit from the original. All other flosses were DMC:. 3771, 783, 322, 3781, 712, 304, and 930. I really like 304- it makes a fabulous red.
