The GOframe system uses a simple mix and match method to create stretched canvases in a wide range of sizes. No specialist tools or training needed. Each bar is made from North American Basswood – the wood of choice for most museum quality stretcher bars. Using a patented set of corners you can create a frame without the need for canvas pliers or staples. Use the 1500 Pro Bar system to create square and rectangular stretched canvases. Or do something different with the Hex Frame system and make six sided stretched canvases. Frames made with the Hex Frame system can be connected together using Collage Clips to create photo collage displays.
