You can stick paper patterns to any kind of wood with double sided sticky tape such as Scotch, Selotape etc. Only short pieces are needed, say 1 inch long along each edge and 1 or 2 in the middle. Easily peels off with no trace and of course no smell or health hazard as with sprays.
Also 2 identical pieces can be stuck together whilst cutting or sanding and peeled apart if you do not use too much tape.
