So, using a 3M spray adhesive, dust the back of the stencil...too much might make sticky globules that remain on the tee, and too little may result in the stencil moving during the next process. Place the stencil on the tee ensuring there are no wrinkles, pat it down to have every detail make contact. Use a foam roller with speedball water based screenprint ink and lightly roll the image through the stencil. Make sure to not water your ink down (unless its old and drying out), press too hard on the roller, or have your roller too sopping, as any of these errors may result in unexpected detail blow-out....no one wants this....unless they do. Use a blow dryer on maximum setting, and heat, to dry the shirt in between layers of ink. It took many runs of my roller to get this opacity on this black tee. Afterward, also on maximum setting, iron the shirt inside out over the printed area for at least five minutes. Viola!
