I like the look of the walnut in a picture frame. In the video he gets confused a couple of times. If you are concerned that, that could happen to you. Just do a standard frame then just cut it in half at the correct angles.
He ended up attaching the frame to the wall with Velcro straps. You want to be careful when bending acrylic. The key is to distribute heat evenly also it is very hot so don’t burn yourself. The acrylic needs to be pretty thin for this kind of project otherwise you can’t see the picture clearly.
