If you do it the same way you make a sign, ie, cut the vinyl and
weed it on the backing as intended and then transfer to the copper
and acid etch rather than sandblast, it doesn't take long and is
not too hard.
You cannot do small shapes or holes, though. I had to modify the
layout of my boards so it was just simple rectangular shapes and
not small pads connected by narrow traces.
I could have done smaller shapes, though, if I'd not been using
really old vinyl and an old dull blade. ;')
You'd be surprised how small some vinyl cutters can cut. However,
the thick sandblast resist vinyl/rubber must use a shallower angle
blade and therefore is limited in how small a shape it can cut.
