My father used to spend hours in hardware stores and I have inherited this tendency except that like all artists I love to browse in art supply shops. Nothing is better than having some new materials to play with.
In the States I love to visit Dick Blick and Pearl Paints, in Sydney, Oxford Art Supplies and there are several dens of temptation in Fitzroy, Melbourne.
Since moving to the country I have been a bit apprehensive about how I will source supplies. I can tell you that Dick Blick DOES ship to Australia and Melbourne Etching Supplies send parcels very efficiently and now I can recommend a new supplier. Art Materials Online is a Mornington Peninsula art supply company providing a fast and efficient mail order service and they stock my favourite Matisse Flow Acrylics. Check out their website.
