Kwik Sew

Kwik Sew (1967–2022) was founded by Kerstin Martensson, a Swedish engineer and sewing teacher. She prioritized "industrial" shortcuts that made sewing faster without losing quality. These patterns dominated the market for knits and stretch fabrics and focused mainly on swimwear, lingerie, and activewear. Printed on thick white paper made them durable enough to be traced and reused many times, and were mostly multi-sized.
