Does Hobby Lobby or Michaels in Houston sell silkscreen supplies?
Why not give them a call? I am assuming you are asking for the basic low-end screen and inks. I found this one company that has high-end supplies: http://www.mcbeesupply.com/mcbeeB_suppli⦠However, a good source for art supplies of all sorts, worth looking into, is Dick Blick. Here’s the URL to their page on screenprinting supplies: http://www.dickblick.
