Read the instructions on the iron on studs; the rest I've done according to the instructions on there.
Step 2
Cut out the stud pieces (still keeping the film on), but place them around so you can plan how you want them to be and to see that you have enough studs for your project.
Step 3
Iron your t-shirt over the areas you want to put studs on.
Then start putting the studs on there, leaving the plastic film on top of them.
Then turn your shirt inside out. Follow the ironing instructions on the stud packet.
