It's a Stitch Up Introduces 'Karma Blend' Fiber

It's a Stitch Up, based in East London, was launched in 2015 with a mission to empower crafters with ethically-sourced materials. The company's dye studio creates hand-dyed yarn and knitting patterns for the ethically-minded. Suzie Blackman launched the company's blog in 2008, which offers patterns, tutorials, and reviews. Karma Blend was created out of a desire to avoid plastic-based vegan fibers, offering a biodegradable alternative with a similar feel to synthetics. The blend consists of 50% bamboo, 25% mint, and 25% recycled sari silk. The sari silk adds vibrant bursts of color and a tweedy effect to the yarn. Bamboo fiber is soft, smooth, glossy, absorbent, antibacterial, water-efficient, and compostable. The bamboo used in Karma Blend is OEKO-TEX 100 certified and processed using a closed-loop system. Mint fiber is a new-to-market cellulose fiber with a fine texture and slight crimp, similar to ultra-fine merino wool. The sari silk is sourced from India, transforming waste into a useful fiber. The global bio-based textiles market was valued at approximately $49.84 billion in 2024 and is projected to reach $81.31 billion by 2030. Plant-based materials accounted for the largest revenue share at 63.9% in 2024, with the apparel segment leading the application sector at 51.2%. The sustainable fabrics market is expected to grow by USD 28.9 billion from 2024-2029. Ethical sourcing ensures fair labor practices, safe working conditions, and minimizes environmental harm throughout the textile supply chain. Certifications like GOTS, OEKO-TEX, and Fair Trade provide assurance that manufacturing partners meet high social and environmental standards. Consumers are increasingly demanding transparency and ethical production, influencing brands to adopt sustainable practices.
