I use Winsor and Newton, and CRYLA professional acrylic paints.
I varnish the finished painting with artist quality professional matt finished varnish. I always paint down the sides of a canvas that are ready to hang.
I use Sennelier artists oil pastels, and always seal them before having them framed. So there is no danger of smudging.
I use Winsor and Newton and Loxley Gold canvases and canvas boards.
I occasionally use 400 gms acrylic paper for works behind glass.
All my framed artwork is done by a professional framer.
