all you need is a butter knife and be prepared to use your fingers
I purchased these studs from studsandspikes which is the best website for whatever type of stud your looking for, not to mention cheap. I bought a bag of silver studs (above), gold small spikes and silver large spikes which came out to a total of $10 for about 150+ studs! Here's a coupon I found online, just enter 'freebag5' and you will get a bag for free from your total. Your welcome, haha!
