Anyone know? A3 or A4 would be nice! John Larkin guarantees it will increase my IQ by 10 points and allow me to become a Real Engineer at last. (I tried printing out a faint squared pattern on my laserjet and it's not bad. But I feel I am missing out on the true experience). -- John Devereux

(Which might have something to do with the apparent IQ increase.) ;) If you aren't allergic to inches, the good stuff is 1000H 1010 with the blue fadeout grid. Their international dealer list is at http://www.clearprintpapercompany.com/media/dealers/international_dealers.html There's one in Germany and one in Italy.

US-made, but when I was living in Europe they were occasionally available then. A very good stationery store may even be able to order the Clearprint pads for you. Or EBay, ask them if they have ruled varieties: http://cgi.ebay.co.uk/50-sheets-of-A4-Translucent-Paper-%2F-Vellum-140gsm-!!!-_W0QQitemZ160370772291QQcmdZViewItemQQimsxq20091020?IMSfp=TL091020012003r931 -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
