🟢measure_fabric_shrinkage(length_before, length_after, width_before, width_after, unit)
Calculates fabric shrinkage (or growth) from a swatch measured before and after washing and drying: length change along the selvedge, width change across the fabric, and the change in area. Use the same marked distances before and after, in one unit (cm or inches). Positive percentages are shrinkage, negative are growth.

}🟢plan_fabric_length(usable_length, shrinkage_percent, extra_length, shop_increment, unit)
Works out how much fabric to buy before washing so that the usable length needed remains afterwards: required length = (usable length + extra) ÷ (1 − lengthwise shrinkage), then rounded up to the shop’s selling increment. Works in metres or yards (any one unit). A negative shrinkage rate means growth.
