Double hand-primed, 340gsm cotton-duck canvas stretched onto a 23mm deep finger-joined, kiln-dried obeche stretcher, yielding a final stretched depth of 25mm.

The stretcher bars are rebated at 45 degrees to lift cloth away from the frame.

Crossbars are installed at 1000mm intervals, in which case a 7mm beading is fitted to lift the cloth away from the crossbars, yielding a finished stretched depth of 32mm.
