This framing work was large….top to bottom 1450mm and some 720mm wide. The difficulty in framing was that the item was hand-made paper (from Laos) about 3mm thick!
It had no willingness to go flat; it was heavy, it was a long way out of being a rectangle.
The frame we used is Oak with a deep rebate and that accomodated the undulating nature of the work. In the photograph, the white ‘tracers’ are reflections from light in the facing window, not a blemish in the work.
