I have gone to 16" x 20" in this one. Using a heated pallet, brushes, iron and nib. There are many layers in this piece and with a buff at the end to bring out the shine of the wax. This was painted straight on the backboard of the frame. There is no need for glass as the wax protects itself. All that is need is a gentle buff with a soft cloth now and then to bring it back to it's original glory.
