Thanks for the responses! Some nice leads there for sure! Thanks for the link Barry - I have not come across the specific paper I want, but the site has a lot of other things that I need, especially resins and gums, thanks! Roy - I have googled for hours, it's a failing of mine, but I couldn't find an online store in the UK, which is the very first thing I tried. Lots of Strathmore 500 bristol board, but I want very thin paper. I feel another google session coming on...

Thanks to all,
Neil.
