Well, you see, when you manage to gouge a large hole in your wall and you need a quick and easy fix to hide it- THIS IS YOUR ANSWER!
Or, if you just want some super cool original art on your wall.
Cut your fabric into three pieces (one metre per canvas) and lay one down wrong side up.
Place your canvas (face down) in the middle of the fabric to make sure you don't have too little/too much fabric.
Cut the fabric to size if needed.
The fabric should be just long enough to over the rest of the wood on the back of the canvas.
Water down your glue (about 1:1 ratio of water to glue) and mix it together well.
Flip over your canvas and spread a generous amount on all over including the sides.
Pick up your canvas and place it in the position you'd like it on your fabric (still wrong side down).
Smooth out any wrinkles or bubbles that you see have formed and leave it to dry.
Repeat the above step for each canvas.
Once dry, flip your canvas wrong side down.
Glue down the remaining fabric on the back of the canvases; folding extra fabric down and gluing them. Cut off extra pieces of fabric if you wish.
*This part doesn't matter too much as it won't be seen once the art is hung.
*Also, I choose to let the canvas dry before gluing the back because the first time I did this, I pulled too tightly and the fabric bubbled in the front. It's really up to you!
Let the canvas dry again and fasten on your hanger.
For this part, i improvised and used some old wire. I simply folded about 15 inches of wire three times (resulting in about 5 inches), twisted the ends so they stayed, and hot glued it on to the top/back of my canvases!
