Cotton Lawn

Cotton lawn is a fine plain weave built from high-twist combed yarns at a high thread count, which gives it a smooth, close surface and a body that reads crisp in the hand while staying light. Weights run from about 70 g/m² to 110 g/m², putting it below poplin and near voile, though lawn is tighter and less open than voile. Liberty of London Tana Lawn is the reference cloth for the type, its fine yarns carrying dense small-scale prints without the design blurring across the weave.

The cloth is semi-sheer, so pale garments often want a lining or a self-facing, and darker or busy prints hide the show-through. It presses to a sharp crease and holds it, which makes it good for pin-tucks, narrow hems, and the fine detail of heirloom work. Drape is soft with a slight spring, so gathers stay full rather than collapsing. The tight weave frays less than muslin but the yarns are fine, so a French seam or a narrow rolled hem suits it better than a bulky finish.

Lawn goes into blouses, summer dresses, full-skirted garments, and lightweight linings where a heavier cloth would add unwanted weight. It sews cleanly with a fine 60/8 or 70/10 needle and a short stitch length, and it wants sharp shears and pins because the smooth surface shifts under a dull blade. Pressed seams lie flat and near-invisible, which is why the cloth rewards care at the ironing board more than speed at the machine.
