Gentle Arts Sampler Threads and Simply Shaker Threads are hand over-dyed, 100% cotton floss in 10 yard, 6 ply skeins. The Gentle Arts notes that the colors are considered colorfast.
Although great care and detail is taken during the rinsing process, there is a slight chance that some surface dye may remain on your individual threads.
COLOR NOTE: Your computer monitor may show a color that may be lighter or darker than the image shown due to the hand-dyed nature of the threads.
