Step 1: Materials needed
-Article of clothing
-Something to put holes in fabric (in this case- tweezers).
-Something to fold stud prongs down (I used my thumbs, and by the end, they were soooo sore. I suggest using needle-nose plyers as I attempted to use my tweezers and ended up cutting myself when they slipped off of the prongs)
-Anything with a straight-edge, such as a ruler, to get a straight line of studs.
***Studsandspikes.com offer a great deal for getting a bag of 100 "English '77" silver cone studs, either standard or tall, for only the cost of shipping.
Here's my Instructable on how to get their free studs-
Getting Free Studs
Step 2: Figuring out your desired pattern
Step 3: Inserting stud
Step 4: Continue adding studs
Any holes from a stud that you had to remove will tighten back up to the regular weave, or whatever, that the denim starts with, unless you happened to rip the fabric itself.
With leather, the holes are a little more permanent, but can wear themselves back to a normal look, but will most likely always be there.
