We all love oversized art, but we know how expensive it can be. That’s why we are so excited about our new paper. Not only does it work with standard size prints, but it also works perfectly with the IKEA Bjorksta Canvas Frame! We spent months sourcing the perfect paper, it is a vinyl hybrid that fits this frame and allows the paper to snap in easily. It looks beautiful without glass and has a perfectly matte finish.

IKEA sells the Bjorksta frame separate from their canvas prints.

Don't let the IKEA instructions intimidate you, this assembly is easy and really straight forward.
Lay the frame on a large flat surface. You’ll slide the metal L shaped corner brace into the lower channel in each of corner. There are small screws that are designed to work with the provided Allen wrench. The first pass you use the screws to stabilize the frame, then make sure the corner edges line up perfectly, and then tighten the screws completely.
Once the frame is built, it’s time to add the art. As a tip, this part is easier with a friend, especially for the larger sizes.  Lay the print face down, lining up the edges. There ends up being about a quarter inch of overhang. The frame comes with plastic clips that fit inside the lower channel and helps stretch the paper really tight, like a canvas.
Starting on a long side, place the clip into the groove and press firmly. Once you place one clip, use the provided IKEA tool to create a fold in the paper along the channel. Add 2 more clips along this side. Pull your paper taut, and place three clips on the opposite side. It’s okay for the first few clips to feel a little less secure, it's totally normal. As you add more the clips will become more and more secure.
Move along to the shorter sides of the frame and repeat the steps you completed for the longer ends. As you add the rest of the clips, the paper should stretch to the frame. However, you can adjust the clips as needed if there are are any wrinkles that need to be smoothed out. Use the tool again to secure each clip.
If you need to, you can slightly trim the excess corner of the print, so it lays within the frame.
The finished frame is super lightweight. IKEA provides hanging hardware that can be installed with a screw or nail. Use a level or tape measurer to determine height, and the frame sits right on the hardware like a ledge.
