I need to get my hands on a small quantity of glass fibers for use in concrete sculpture, but am finding it hard to find an Irish supplier. I dont wont to be paying for shipping so it needs to be a company near Kildare or Dublin. None of the companies I am finding on line are giving prices for small amounts (all I want is a sackfull to try out) are there any builders providers or diy stores that sell it in small bags? please help!?
