Hide & Cut Pack

A hide is not a sheet of material, and area is not yield

A hide is not a sheet of material. Four leathers in one side and what each can make, why area is not yield, weight against thickness, thread quantities and stitch spacing, hardware and edges. Then the page that decides where a piece fails: what the stitch line takes away. A pricking iron removes about half the material along the seam whatever spacing you pick, the cross-section left moves four times more with leather thickness than with pitch, and on thin leather at a conventional edge distance the piece tears a strip off its side rather than opening at the seam. 10 pages, printable, with a fill-in cutting plan and order sheet.

What is in it

• The four zones of a side: share, firmness, grain and usable fraction
• What each zone is good for, and what it must never be used for
• Why firmness and surface are separate questions
• Real yield against area, for six common parts
• Where the difference goes: zones, trim, and nesting
• Leather weight to thickness, and what each weight is genuinely for
• Thread to cut for any seam, including the tails the calculator omits
• Stitch spacing, and why finer is not stronger
• What a row of stitch holes actually removes — roughly half the line, at any spacing
• The cross-section left holding each gap, by spacing and leather thickness
• Why thickness matters four times more than spacing does
• When the edge is the weak line, not the seam — and the edge distance that fixes it
• Five hardware rules, including the commonest rivet failure
• The edge sequence, and why everything after sanding only adds shine
• The order of work, and the points of no return
• Fill-in cutting plan and hide order sheet

The pack complements the free calculators — they do the arithmetic, it carries the zones they cannot see.
