These DIY studded shoes are so easy to make, just takes a little bit of patience and time.
I decided I wanted a sporty shoe for this DIY, also the fabric of the shoe was soft enough to facilitate the making of the holes.
First just take a white pen (i used a make-up pencil), and mark where you want the studs. Take in consideration how big the stud is, depending on how close to eachother you want the studs.
Make a hole either with the machine you use for adding holes to leather belts,
or a nail, and attach the studs. Voilá!
