In my art work I use acrylic and oil paints.
My favourite canvasses are those made of linen with smooth surface. I also like linen canvasses. Paintings in this store are made on either of these materials.
I buy pre-stretched ready canvasses because they're good enough for my art, I'm interested in exploring shapes, patterns and colours, not so much primer and canvas texture.
When the painting is ready, a layer of Vernix is sprayed over. This is to prevent fading of the paint, and to even out canvas where paint is of different depth.
Most paintings have matt finish but some are gloss.
