Shared Lane Markings Follow MUTCD guidelines to create a marking that measures 40 in wide. x 112 in. long (including chevron). Place sharrow marking in the center of the travel lane, a minimum of 11 ft. from curb where parking is present, or 4 ft. from the curb on streets with no curbside parking and apply spray paint, spay chalk, or sidewalk chalk.
Bike Lanes Follow MUTCD guidelines to create a marking that measures 40 in wide. x 112 in. long (including arrow).Place marking in center of bicycle lane, at a minimum twice per block (start and end of the lane). Increased frequency should be based on local judgment (design speed, length of block, number of driveways etc.).

Print marking to scale on paper and cut out. Place paper over cardboard and trace. Cut cardboard using utility knife or sharp scissors; Ask someone with keen arts / crafts skills to trace / cut.
Cheap and possible reusable for future demonstration projects (wet spray paint / spray chalk will eventually compromise quality / stiffness of the cardboard.
Choose extra large moving boxes that when flattened can collapse further.

Purchase from local hardware or moving supply store.
Reclaim discarded cardboard boxes (extra large).
