Some hobbyists who like making t-shirts really like the screen printing method of making them. One major piece of equipment you need is a good silk screen for this to happen, but who makes a good quality silk screen? That is what I am here to answer for you.
I would prefer one with a durable, aluminum screen frame over the wood. That’s just for longevity. The first brand here mentioned is still a great screen printing screen though. Speedball has been in business since 1899 and got their start doing fine pen-making. They have been in the screen-printing industry since the ’70’s.
