I'm a little late to this party, but as shoreguy mentioned, I think that the Circlist Method - Feel Cut is definitely the best way to go. I've attached the two pages of the PDF as well as my personal example.
I actually wrote a rather detailed description of my process on a reddit thread, linked below. I think I'm going to make it into a stand-alone post on pulledback so that it can be a resource for other folks.
In short, consider reading the below post (apologies for the length). For the tape itself, I HIGHLY recommend 3M's Transpore Surgical Tape. I've tried a lot of types, and that one is by far the best.

Usually i am a spoon-method user, for me it´s no spoon, i´m using a clinical thermometer, doing it while showering, washing my cock and while rinsing off the showergel, pulling my forskin tightback, put the thermometer at the possible deepest point on the innerforeskin and then push the foreskin forward and simultaneously doing the know spoon movement around the cock.
So, that´s my EDC...cause i´m a grower
From time to time i use some tape methods, today i´m trying the autocircumcision method...BUT...it´s been quiet difficult for growers, today the first tape consists of several layers, to make it thicker, the foreskin better slips behind it, muuuch better then a normal layer to fix the whole thing...and it works great.
So i have to find some thick tape and it will go very easily for the future to to do it more often
