I’ve known Jens Boll (from Germany) for many years now, having met him at many UK conventions as well as several German ones. He is a genuinely warm and unselfish person, often spending large amounts of convention time helping Silke or Ian with their supplies duties.
In addition, he has the kind of technical folding skills that I can only aspire to. Here’s a photo of a Fujimoto design he folded many examples of at the BOS convention in York. I added the one penny coin for comparison. This one was folded late on Saturday evening, in a room that wasn’t lit very well. I realise practise plays a large part in skill like this, but I just feel some people have a natural gift for it, Jens being one!
