Turn one sample size into a complete, graded knitting pattern.
Skein is grading software for knitwear designers who need their numbers to be right — not just fast.
Enter your gauge and finished measurements once. Skein computes exact stitch and row counts across 9 sizes (XS–5XL), writes the shaping instructions to match, and draws a live schematic from the counts it just calculated.
SIX CONSTRUCTIONS
Raglan, circular yoke, set-in sleeve, drop shoulder, hat, and sock — each with its own real shaping logic, built from published industry method. Set-in sleeves include an armscye check: Skein compares the cap edge to the armhole it eases into and reports the ease honestly, which is the part of set-in design that most often goes wrong.
EVERY COUNT VERIFIED
The rule Skein is built on: every printed count must be a count the knitter actually has. Table, split, and instructions are asserted to agree for every size, on every launch — 450+ checks across the engine.
ONE PATTERN, EVERY SIZE
Export a pattern and it reads the way a published one does — one set of instructions with every size bracketed in, smallest first, not size after size repeated on its own.
YOUR PATTERNS, EVERYWHERE
Your library, your in-progress projects, your yarn stash, and every PDF you've attached sync across iPhone, iPad, and Mac through your own iCloud account. No separate sign-in, nothing to configure.
A REAL SCHEMATIC, EVERY EXPORT
Every exported pattern closes with a measurement diagram drawn to scale from the same stitch counts as the instructions, lettered and keyed the way published patterns are ("34 (38, 42…)″") — not a screenshot you have to add yourself.
A FREE PATTERN TO START WITH
The Chestnut Raglan, an original relaxed top-down pullover in nine sizes, is built into the app. Free, no email required.
YOUR OWN PATTERN LIBRARY
Add the patterns you've bought — attach the PDF, add your notes and sections, and keep everything in one place.
WHILE YOU KNIT
Skein opens on your row counter, right where you left off. Your row count also pins to the Lock Screen and Dynamic Island, so you can glance without unlocking. Add a price per skein and every size shows an estimated yarn cost beside its yardage.
STITCH PATTERN REPEATS
Enter your motif repeat and every size holds whole repeats — cables and lace land cleanly in all nine sizes, with any deviation reported.
