Leathercraft Math: Hide Areas & Yield, Thickness Conversions, Pattern Layouts, Stitch Counts & Thread Length, Edge Finishing and Pricing per Piece
Plan leather projects without wasting expensive hides. You will convert hide areas and thicknesses, estimate usable yield after flaws, lay out pattern pieces, count stitches and thread length from seam lengths, plan edge work and hardware, cost each piece and price it for sale, with every cell checked as you go.

About this course
This course follows one fictional leather workshop from the hide to the price tag. You convert hide areas from square feet into dm² and m² and compare cuts on price per dm², look up thickness from leather weights and check seam stacks, take off edge losses and flaws to find the real cost per usable dm², fit pattern pieces on a hide in two orientations with INT and MAX, count stitches and thread length for a batch, estimate edge coat and hardware with SUMPRODUCT, compare single-piece and batch times and set wholesale and retail prices with a margin, CEILING and a chart.
