Right before my show this winter I hung many of these canvas sheets on a display panel with clothespins. I then decided which ones I want to be shown. The rest I place in folders.
I use Fredrix canvas pads, 9x12. The Canvas will be glued to a gesso 9x12 board. I glue the canvas to the gesso board with, Artist's Acrylic Polymer Medium. I put heavy books over the glued canvas and set over night.
