A floss estimate is a shopping aid, not a guarantee that a skein will last. Stitching tension, route, starts, ends, and the way you carry thread all change actual use.
Separate strands and skeins
Standard DMC Mouliné Spécial is supplied as an eight-meter skein made of six separable strands. Working with two strands does not mean two whole skeins. The app estimates total strand length from stitch count, the geometry of a full cross, and a travel multiplier, then compares it with total strand length per skein. Change skein length if your chosen product differs.
Choose coverage with a swatch
Two or three strands can look different depending on fabric count, color, and tension. Try a small section using the intended fabric and needle rather than accepting a universal strand rule. Increasing working strands increases the estimate proportionally. A higher fabric count reduces the physical length of each stitch, while scattered stitches can increase travel and fastening waste.
Read the assumptions
The material panel exposes working strands, allowance, skein length, and a path multiplier. The default multiplier adds a rough allowance for thread routes; it does not inspect your stitching method. Suggested whole skeins round each used color upward, so a tiny accent may still show one skein. Compare the list with thread you already own, and keep extra margin for difficult colors or projects where matching a dye lot matters.
Stitch a small coverage sample and adjust strands and allowance before using the estimate as a shopping list.

Our guides offer general planning advice. Chart colors are digital approximations. Choose physical floss from a real color card or your own stash before a large project. Fabric and thread estimates describe full crosses with your entered stitch length and allowance. Backstitch, half stitches, unusual carries, and finishing need separate planning. We do not claim hands-on tests of products mentioned in buying guides.
