I Loosed the knob 1 turn, and dont forget to turn it back up when done,, i put perm marker on the threads so i can see where i am headed.. or need to get back to.
try to keep the hoodie out of press unless printing that as well, as that is the bulkyest.
If you do heavyweight Hoodies, or crewnecks, sleeve the press, like a pillow case.
Hope that helps
