I'm not a professional carpenter and I haven't worked much with wood before. I also lack proper tools.
I made a heart-shaped wooden pendant for my girlfriend with a paper knife and smoothed it out with some sandpaper. It's about 3.2cm long, 2.5cm wide and about 1cm tall, made with red sandalwood (which I believe is a type of hardwood). The base is flat with the edges smoothed off, but the top is more rounder as it goes to the sides. I now have planned to drill a small hole on the cleft and into the center of the pendant, into which I'm planning to screw in an eye bolt (something like this - http://goo.gl/UKjWUA). By doing that, the screw will be going against the grains.
Now my problem is, I don't have a drill. And I don't know how to make a hole in wood by other means on something as delicate as this. Plus I can't take chances, if you know what I mean.
I'd be very glad if anyone knows a solution to this, an alternate method to drill a wood in this pendant.
