Another update:
backbox now has the basecoat done, finished yesterday afternoon it is now ready for stenciling when the paint has had sufficient time to cure properly.. hopefully this coming weekend!
But first, of course tracings of the stenciled designs were done before i did anything to the backbox. Pics below.
Now normally i do two separate tracings (one for each colour/section), stick it down onto the white cardboard i use and cut through the tracing paper and into the cardboard with the scalpel. But for this i used one piece of tracing paper for the two colours, and traced each section onto its own cardboard piece with carbon paper between the tracing paper and the cardboard.. in the 2nd pic you can see a sheet of A4 carbon paper under the tracing paper.
last pic shows the finished stencils ready to use
