@pulserasAG - I am unsure of the specific amount per skein - but I believe I used around 10 DMC Pearl size 5 skeins of each color, and even more for my background of white. Maybe 2 backs of the pllieay bag from amazon.
I want to make this but the watermark entirely repels me. Someone clearly stole this picture from google and made it into a pattern even though it had a watermark
