SpineSew

Generate sewing patterns for hand-bound book signature assemblies

Creative AIFree

SpineSew calculates sewing station positions, cord spacing, and thread paths for Coptic, kettle-stitch, long-stitch, and link-stitch bookbinding methods. The tool adjusts station placement for spine curvature compensation based on paper weight and signature count. Thread length estimation accounts for swell buildup across signatures to prevent spine distortion in thick volumes.
