Got a blank canvas or a piece of art you need to mount? This is a simple, sturdy wooden frame you assemble yourself. It comes as four rectangular wooden strips that you fit together to create a 16x20 inch frame (that's about 40x50 cm). It's designed to be a 'stretcher bar' frame, which means you stretch your canvas over it and staple it to the back for a tight, professional look. The wood is good quality and sturdy, so it won't warp easily and will hold your artwork securely. It's perfect for oil painters, photographers printing on canvas, or anyone doing DIY wall art. Assembly is super easy and doesn't require any special tools. Once you've got your canvas secured, you can either hang the frame as-is for a modern 'gallery wrap' look or put it inside a larger picture frame. A must-have basic for any artist or crafter's studio supplies.
