I've tried a couple of ways of making canvas panels including using Miracle Muck as the adhesive. My latest attempt is my favorite and not as expensive as buying a dry mount press and the adhesive sheets. These are the materials you will need in order to create a panel as good as the commercial ones.
Birchwood panels cut to size
Canvas cut to size with an extra 1/8th of an inch on each side
Lamin-All (liquid adhesive)
house painting brush
First dilute the Lamin-All with water. About a fourth of a cup of Lamin-All and 1 Tab. water. Stir and store in plastic container.
Next brush a thin coat of Lamin-All on one side of the wood panel. Let it set for approximately 30 minutes until it goes from a milky color to clear.
After it turns clear, position the canvas on the board, cover with cloth, and press with the iron (set to perm. press). Iron for about 3 minutes-more if the board is larger.
I completed five panels during this session in an assembly line type production system. And the finished products. Tadaaah!
