I am trying to make a few shirts for my wife and crew at the local EMS location. White on black. I would like to add a reflective material to the ink for nighttime use. Should I mix it with the ink first, or sprinkle it on after it is printed while still wet? It is glass powder like here. http://www...

Can you heat press silk screen mesh (160) to remove the wrinkles before stretching it?

I have seen this on youtube and on several how to tutorials. Can it be done effectively to get started? If not, what mesh is best to use with speedball inks?
