wanted to try my hand at block dyeing, yet the videos I see feels like I are missing a step. for the project I see is 2 color or one color with veggie leather not dyed. is it just wrapping cloth (not sure if can be any fabric like old t shirt) over block of wood. put dye on give movement to soak in touch of paper towel or other piece of leather to get extra dye off before wipping over leather project you want to dye. or does one need to put a coating of somthing over the leather area you do not want dyed, trying to get some help in the area
