Metal -- Yes, I get my information first hand, from very reliable sources.
I have been told by a young woman who interned for him while she was in school, that she made actual patterns for his designs. I believe what she tells me on this because I've known her for a while. I also know a guy who interned for him, and tells the same story...the interns go to Patriks place, and make tons of patterns...I dont know how much of that work actually makes it into his collection.
I also am familiar with Patriks postings at school where he looks for a crew of interns every semester...he states that interns will make his patterns and some sewing. As far as I know they are not paid (other than school credit).
Believe me, the interns like the experience they are getting, compared with what interns do for other designers and companies (clerical work, running errands). The interns learn a lot, hands on...though they do work long hours. I remember that I chose not to go there because I didnt like the quality and style of his collection.
