i thought i`d post it officially: i just got back from a short trip to austria to get edges and received some base material from gurit - so if anyone from europe needs base and edges, just shoot me an email or something like that.
base is 1,5mm thick, black, 150mm wide. edges are 2x2mm
answered your mails. maybe there is a way to get hands on transparent topsheet if you both wanted some. i run out of it and i need a certain quantity so that i can order some new one.
but generally things are going well
