With the gallery frame, you can frame a gallery or regular profile canvas without the canvas sticking out the back. You also have the gallery photo frame with glass, which is deeper and will stand out more on your wall.What is a floating frame?As the name implies, a floating frame is designed in such a way that your artwork appears to float within the frame; it is not pressed behind a piece of glass. Because of this illusion, viewers gain a sense of 3D depth. Floating frames are particularly suitable for stretched canvases. Unlike traditional frames, floating frames feature a front-loading design; the canvas is dropped in from the front and secured in place from the rear. They allow you to see all the way to the edge of the artwork so none of it is obscured by the frame. If you’re looking for a gallery-style look, floating frames are your answer.What is a mat?A mat is a piece of cardboard (usually with an opening in the centre) that leaves a space between the photo and the frame. It is only suitable for paper artwork, not canvases. When a mat is used, there is usually a glass panel to protect the photo and the mat. Finally, when you see the words "acid-free or conservation", it means that the mat is archival quality and will not fade, yellow or alter the work over time.
