PS: This is my first instructable, so if you have any questions or anything isn't clear enough, let me know. The model isn't me, but rather someone who was nice enough to let me shoot him for this, so be nice or STFU. Thank you. :)
Step 1: Get it together
1. Basic knowledge of sewing + a sewing machine/black thread. You could sew this by hand, but it'll take forever...
2. Old black jeans you don't want anymore, or a scrap of similar fabric
3. A few inches of black Velcro
4. Your choice of pronged studs, be they pointy or rhinestoned. I got mine cheap(about $3 for a bag of 100) from Spikes and Leather. You'll definitely have extras. It's okay. You'll put them all over everything, trust me.
5. Needle-nosed pliers(or any pliers, 'cause I couldn't find them when I made this a second time), or especially tough fingernails, if you're really punk rock and you're not against bleeding all over it. No really, just use pliers...
