Colour your Neck Gear using Fabric Dye or Sharpies
Put plastic (page protectors) in and under the Neck Gear. This insures that first, the alcohol does not spread to the other side of the Neck Gear and secondly, so that no marker colour will mark the surface you are working on.
Second Threads White Neck Gear Colouring Instructions Using Sharpie Markers
Use isopropyl alcohol
Sharpies (other brands don't work as well) & test sharpies on rag or paper towel before marking Neck Gear.
Not all colors work well. We had a light purple bleed to yellow. Metallic didn't seem to work. Some colors bleed but leave a solid line behind.
(There are lots of YouTube videos on this.)
Mark up neck gear.
Put plastic into neck gear to keep sides separate and put plastic under neck gear to protect work surface. We used page protectors because they fit just right.
Spray or carefully or pour isopropyl alcohol onto neck gear. The wetter it gets the more the marks spread. Do the entire neck gear front and back at the same time, otherwise you will get marks. You can get everything wet again to get rid of these. Please note that if you don't hang the neck gear to dry the side that is resting on the plastic will be more faded.
We have found that when we wash the neck gear coloured with sharpies it does fade some. Keep your colours intense.
Don't smell the neck gear while it is wet. There is alcohol evaporating, make sure you have good ventilation or put it in a different room.
Once dry, put on and enjoy your wonderful creation!
What Not to Do!
Here is an example of what happens when the Neck Gear is not equally wet. This can be fixed by rewetting the Neck Gear.
