Tips from the Shed

“Square canvases love contrast—paint the edges a complementary colour for an instant frame effect. Mist the back lightly before varnishing to keep tension drum-tight.” 

Real Reviews from Happy Artists

⭐⭐⭐⭐⭐ “Great products and fast delivery! Really happy with my order and will order again soon. Thanks Art Shed!.”

⭐⭐⭐⭐⭐ “I have recently used these canvases to create a set of six individual boards that create a very modern contemporary presentation using acrylic medium. The boards were easy to paint on and the surface has a nice clean finish. I have just ordered 12 boards because friends have asked me to create pieces for them. I highly recommend this product for its quality and art shed for its great service.”
