Proverbs is an exclusive blend of cotton and linen; 5-ply, sportweight. The more you wash and wear it, the softer it becomes!
You may experience some color bleed when washing/blocking for the first time. It is completely normal with cotton yarn due to the different dyeing process than wool. Each skein is rinsed seven (7) times to remove as much excess dye as possible, and has been treated to not bleed onto itself if you are using more than one color together. It should not affect the depth of color what-so-ever.
