Ida Wirak Trettevik (b. 1989) is the woman behind Witre design, a website of knitted clothes and patterns. She is followed by more than 73,000 Instagram users. The first patterns launched in 2018, and from the start, Witre design has been about finding a modern expression for knitted garnments and designs, creating patterns that will inspire to knit one's own wardrobe - piece by piece. A strong motivation behind the concept is also to help knitters create pieces of good quality and longevity, adjusted to the individual knitter's own preferences.
