'Anti-Social Social Club' bleach print block for T-Shirts

I read this article on bleach printing and came up with a design for printing onto a t-shirt or hoodie.

Steps

1. Print the design using a bleach proof filament. I like PETG
2. Stretch the t-shirt or hoodie over a piece of stout cardboard or other board that will hold the material tight
3. Spray the printed block mold with a goodly amount of bleach so that all raised surfaces are covered
4. Place the stretched fabric on top of the bleach coated block mold and press tightly for a couple of seconds to ensure accurate transference of bleach onto fabric
5. Quickly flip the material/board image side up and immediately begin drying (both outside and inside) to ensure the bleach doesn't creep
6. When dried to desire let it rest for a bit to ensure it is good and dry before washing
