I tend to break a lot of buttons so I decided to find/make one that didn't pop off my pant's. After some thought I decided that a penny would make a great button, or even a quarter or dime.'
Step 1: Preparation
The tools you will need.
1.drill with small bit, bit size depends on how big you want the holes.
3.Center punch and hammer
5.vice grip pliers
Step 2: Chooes hole location
Use the center punch and hammer to make dents at the location of each hole. Doing this helps keep the drill bit from wandering.
Step 3: Clamping
Use the vice grips to clamp the penny in place. Don't squeeze the penny to hard or you will mark and scratch it.
Step 4: Drill the holes.
Drill the holes out, then take the dremel tool and clean up the holes. make sure you get all the bur's and taper in the holes to insure that they don't cut the thread when pressure is applied to them.
Step 5: All thats left is to sew button on.
I am leaving this one up to you. All and all it makes a pretty durable button that will not get brittle and crack.
