FabricCalc: Yardage Math for Real-World Sewing

Field notes

FabricCalc separates common home-textile jobs instead of treating every project as interchangeable rectangles. Its descriptions account for fabric width, directional grain, nap, pattern-repeat alignment, half-drop repeats, fullness, hems, lining, pleats, and staple wrap. The homepage says results include both a cutting list and a layout diagram, while the extract does not expose the actual calculator forms or outputs for verification.
