I'm liking the derailment, cause I've already answered the OP question and I want to make some hash.
I have made QWISO a few times. I don't like it enough to try to do it again, ever. I thought I was pretty good at making it. Not my cup of tea.
I just ordered some bubble bags and hope I like what I can get out of those. If not I'm ordering some silkscreen frames.
that's exactly why there are different methods.
I looooove my qwiso
