There are no "teks" to my knowledge.. there is general information around but nothing like a concise down to the point, 'you can do this with your eyes closed' type of guide.
Laying blotter seems to be pretty frowned upon here because of the things that could potentially go wrong.. you definitely want to make a few trial runs at it before you attempt to do so with any active substances.
As far as Anon0631 being rude, well, the question has been asked a million times on the internet as a whole and another large number of times here on bluelight as well.. there are numerous threads that detail how to go about it.. but as I said, there are no foolproof methods that 'teks' usually seem to be geared towards. Because there is no foolproof way to properly lay blotter.
