How does the tool account for leather waste?

The `calculate_yield` tool applies a waste buffer of 15% to 25% to the net area to account for irregular hide shapes and natural defects.

How is thread length calculated?

The `get_material_consumables` tool calculates thread length by multiplying the total seam length by four, which is the standard requirement for a manual saddle stitch.

Can I manage grain direction for my pieces?

Yes, you can specify grain requirements in `get_net_area` and `suggest_cutting_layout` to ensure pieces are oriented correctly for structural integrity.

More Details Connect to Claude

This MCP server provides deterministic calculations for leatherworking projects. It helps crafters determine the total surface area of pattern pieces using get_net_area, calculate the number of hides required with calculate_yield (accounting for 15-25% waste), estimate thread consumption for saddle stitching with get_material_consumables, and receive placement strategies via suggest_cutting_layout.
