Cloth, chalk, and calm math
GrainLine Sew Studio is the fabric-and-pattern planning desk for home sewists and small makers who refuse to guess at the cutting table. Choose a garment block, apply silhouette ease from built-in tables, and watch finished measurements update with live before/after deltas. Set real fabric widths, directional nap or one-way prints, repeats, and shrinkage—then get yards and meters with a plain-language waste breakdown. Arrange scaled pieces on a grain-locked layout that snaps 0°/180° (cross-grain only when you allow it), flags collisions, and shows remnant strips. Export a cut sheet and notions prep list, keep multiple Wearer Fit Cards offline, and open six seed projects already filled for 45" and 60" goods. No accounts, no tracking—just calculation, layout, and cut-once confidence.

The planning desk
Nap & Width Yardage Desk
Lock fabric width (cm/in), nap or one-way print, H/V repeat, view count, and shrinkage buffer. Output yards and meters plus a clear waste story before you buy.
Grain-Locked Cutting Layout
Place scaled pieces on a rectangle matching your goods. Snap 0°/180° with grain lock, optional 90° only when cross-grain is allowed—used length, remnant strip, and collision warnings included.
Bias, Seams & Notions Math
True-bias strip lengths, continuous binding yield from a square, seam-allowance switchboard (home vs light-industrial, French/plain/serged), and a checkable notions prep list from garment type and fabric hand.
Wearer Fit Cards & Cut Sheets
Save multiple wearers with close/standard/relaxed ease; print measurement cards for the table. One-tap PDF/CSV-style cut sheets with layout thumbnail and shopping-ready notions.
Starter Library & Store Widget
Six complete seed projects—Basic Woven Tee through Simple Shirt Dress—prefilled for 45" and 60". Home board badges yards-to-buy; Lock Screen widget shows active project and next cut length.
