LOML wants me to make a box like the one in the photo. I don't know how the sides are made. The box is 4-1/2 High x 12-1/2 long and 8'1/2 deep. Any one have any idea (and instructions) of how to make the curved sides on a box like this. 12" seems a bit long to try to cut the curve standing on end on a band saw.
