... ah a prayer carpet ... so does this mean that you were in a state of prayer while working on this carpet? I like the Bic - haven't tried the yellow ones - always look for ballpoints that will give a variety of line - this one seems to do it - I might try a prayer carpet myself...
I do Surautomatism - I do a big squiggle and find stuff in it - right now I use ball point pen on paper with crayon. I have been working like this since 1989 - with a many different types of media.
