My initial reaction was, “Oh, these are too heavy to be carried on and off stage.” But the beautiful surface pieces (minus the structural 2×4’s) were perfect. 3×1? 3×1/2? Whatever.
I took two pallets apart and built a 3 foot by 2 foot “sign” with a “kickstand” on the back so it could stand alone. Then I sanded it so it could better take the lettering, and white-washed it with watered down white paint to make it look more like driftwood.
FYI, the final lettering is darker in this picture, thanks to sharpies. Actually, cheap dollar store sharpies which splay out, but are still more controllable than paint and brush.
