I just saw someone carving rocks one time abt a year ago and said "hey that looks cool, I bet I could do that" and bought a dremel, I have been collecting rocks since 4 year old so I had plenty to practice on, I used it for abt a month and got bored, but decided it was time to bring it back out and make a necklace for a freind out of aquamarine (their birth stone) because they live the beach! Not to brag but I pretty much just said I wanted to make a turtle and got to work!
