I have been knocking out the signs by the dozen during the holiday season. On Christmas Eve (Wednesday) I did four signs, about one every hour, for "bargain bubbly." These are inexpensive sparkling wines that you can buy a lot of to pass around at New Year's. The signboards are about 2 1/2 feet square, and the writing is done in opaque acrylic markers on Masonite painted with black "chalkboard" spray paint. I think that Trader Joe's must keep Rust-Oleum in business by using far more chalkboard paint than would be called for in "normal" uses such as classrooms or kids' rooms. I think about how much of the stuff we use when I have to go get more. Our markers are also "re-purposed" (there's another good 2000s buzzword for you). They are originally marketed to crafters who like decorating wooden knicknacks. When I order new supplies I wonder what the vendor (a craft supply place called "Woodcrafter.com") thinks we do with all the dozens of markers we buy. I helpfully added on one order that we were signmakers, just to keep things from being too unnatural.
Oh by the way, Merry Christmas everyone, and a happy Solstice and Chanukah too.
