2015년, Calla는 여러 패션 브랜드에서 버려지는 섬유 쓰레기에 회의감을 느껴 여성의류 브랜딩을 과감히 중단하였고 전 세계 다양한 고급 브랜드들과의 협업에 집중했습니다. 이러한 협업정신은 그녀가 유럽명품과 Berbebr 공예 공간에 대한 호기심으로 이어져 다양한 색감과 섬유 재활용을 통해  생산되는 부샤로이트 러그를 발견했고 유럽의 럭셔리 패션 분야와 베르베르 공예를 접목시키기 위해 여러 장인을 찾아다녔습니다. 그 결과로 부샤로이트 프로젝트를 기획했고 섬유의 재활용과 부족민의 공예를 지지하는 두가지 핵심 주제로 지속가능한 디자인에 초점을 두었습니다. 오랜 역사의 기술로 만드는 여성장인과 협업하여 현재는 모로칸러그 컬렉션과 업사이클링된 베르베르 뮬슬리퍼 컬렉션을 전개합니다.

Paris-based designer Calla Haynes grew up in Toronto and moved to New York to attend the Parsons School of Design. Upon arriving in Paris more than a decade ago, she began working at Rochas and Nina Ricci, finessing her textile and print design skills while absorbing the savoir-faire unique to French luxury houses.

With the launch of her namesake label in 2009, Haynes established a fresh balance between refined and relaxed. The collection was heralded by the fashion press including Vogue and Elle, and Haynes was the subject of a profile in the New York Times.  Printemps, Harvey Nichols, Isetan, Opening Ceremony and other leading luxury retailers carried CALLA.  Through her label, Haynes was a finalist in several design awards including the Grand Prix of Design of the City of Paris, the Dorchester Fashion Prize, and four nominations for the ANDAM Award.

Placing CALLA on hiatus in 2015, Haynes focused her attention on collaborations with diverse and high-end brands around the world.

This collaborative spirit inspired Haynes to seek out artisans in Morocco to explore the space between European Luxury and Berber Craft.  The result is "The Boucharouite Project": initiatives that focus on two key themes of Sustainable Design - recycling textiles and supporting traditional craft. This includes a collection of rugs made in collaboration with female weavers, and a collection of Babouche slippers handmade in the souk of Marrakesh using upcycled vintage Berber rugs.
