Gerd's long-standing and successful relationship with Robin Day is recorded in a letter he sent her: "Of all the rugs which I have seen, only yours have got the character enough as a background for my new designs of furniture to be exhibited at ‘La Triennale de Milano 1951’. Please can you weave for this Exhibition a rug of the approximate size: nine feet by seven feet..."
Together Gerd and Robin Day discussed the rugs, not only for Milan but for the forthcoming Festival of Britain. Robin explained to Gerd that he was designing his furniture with exclusive rights to S Hille & Co, a furniture manufacturer located in Watford.
The three black and grey rugs exhibited at La Triennale de Milano as a background for Robin Day's furniture proved to be a huge success, with both Robin and Gerd winning a Silver Medal. Following this wonderful achievement, Leslie Julius of S Hille & Co contacted Gerd asking to represent her, and to discuss showing her rugs with their furniture in the new Hille showroom, soon to be opened in Albemarle Street, Mayfair.
