Por Projeto

Almofada 45×45 cm: 0,5 m. Cortina (janela padrão): 3-4 m por painel. Toalha de mesa: 2-3 m. Saia simples: 1-1,5 m. Vestido: 2,5-4 m. Tecidos se vendem em largura (laize) de 110 ou 150 cm — a laize afeta diretamente a metragem. No Brasil, os centros de tecidos como a Rua 25 de Março (SP) oferecem os melhores preços.

Perdas

Tecido liso: +10%. Estampado com repetição: +15-25%. Compre sempre do mesmo lote.

⚡ CalcWolf Insight

The most expensive sewing mistake: buying one yard too little of a fabric that gets discontinued. Fabric stores cannot reorder from the same dye lot, and colors vary between batches. Always buy 10-15% more than calculated. Leftover fabric makes great throw pillows, tote bags, or test pieces for technique practice.
