In one of the advertising "newspapers" (you know, the ones you get, if you have a store-card for the supermarket etc.) there was an article about a lady who creates knitted food installations. The article is available online (in german).
That made me google for her - and I found her website and her blog. I do love some of the photos there - there is even a free (german) pattern for a knitted sausage :)
I apologize that all the links are to german-speaking webpages, but really like the idea - and I like her knitting philosophy as expressed in the article: "[Stricken ...] helfe, ein Trauma zu verarbeiten, und tue auch Depressiven gut. Am
besten sei Stricken ohne eigentlichen Zweck, .... Wenn man wie sie ohne Muster oder Vorlage arbeitet und
sich das Objekt einfach vorstellt, fokussiert sich der Geist aufs
innere Bild und lässt schlechte Gedanken vorbeiziehen."
Roughly translated: "Knitting helps to coping with trauma and is even good for depressive people. The best is knitting without a purpose ... When one works like her without patterns and just imagines the object, the mind focuses on an inner picture and lets bad thoughts disappear."
