If stitching only the sampler with model specifics, you will need one skein of each color listed.
Floss estimation is for stitching the sampler and smalls shown as directed (one strand of floss over-two linen threads) on 40-count linen. DMC equivalents are only approximate, as there are no exact equivalents for hand-dyed floss. For best results, I strongly suggest using the Weeks Dye Works cotton floss.
