My process is an extremely organic one: I choose a texture, then start mark making, but at this point I start listening to what the canvas wants and needs. I never work with a design/image in my mind. I totally immerse myself into the canvas and let the creativity flow instinctively. This is also the same way I add colour to my canvas.
The textures I use are many and varied from shredded paper to grit; the rule of thumb is if I can use it, I will. I tend to add the texture with a pallet knife; however, if it makes a mark then I will use it. I find that everyday items make amazing texture – I love an orange bag net.
