So at least through Saturday. Since the Diva suggests "Quandry" that is what I used for Saturday.
I note that everyone has different step outs that work best for them. Mine are a series of pencil triangles.
I make the pencil lines VERY lightly and then erase (I know that is a bad word in Zentangle) but really sometimes it just works better than way. I "could" leave the lines in and make then part of the tangle, of course.
