no i dont-
just thought id tell you that.
but there is a tutorial on how to make a boat on the other part- this barge- and that was a paper mache remote control boat- fully waterproof- looks like a boat- im guessing same waterproof principles might apply- you could send that chap a message maybe- he really knows his stuff and his boat is perfect.
but im sure someone will have detailed answers for you soon- god luck with your vase- sounds good- its it was me- id do strips of old books- and id do a lot of them- thats kind of how id start- but i wouldnt know how you made it waterproof. i think it just need s a few coats of some kind of resin- ill read your answers as im intreagued myself now- goodluck

i had a look at that article- it was how to make a narro boat- chris shilling- if my memory serves me right- well he simply painted his boat with black car dy paint- stands to reason that cars ahve to be waterproof and protect against rust- but would this be right look for a vase? i think not- too thick. in the gallery there are some vases- and te artists email addresses are there- all depends on whether you get replies. i suspect some kind of varnish wold work- a boat varnish sounds good to me.
