Hi Vic,
your pens are, as always, stunning. Do you use the medium ca for serpentine blanks as well as your others? I mean do you have time before the glue goes off. I just finished another with the drinks can method, looks quite good I think. Looked at the polypropylene, got a bit muddled on that, could not see any half mill stuff. Would thicker bend ok. Sorry to be a pain!
