Blackberry Macro

I read an article that told me about a mounting ring that will allow me to turn my 50mm lens around, thus turning it into a macro lens. After going on a bit of a hunt and doing some research, I found out that this is in fact true, but these rings aren't very popular in Canada, even difficult to come by. I was told of a bunch of other options, such as filter kits, extension tubes, etc. And then it dawned on me, why don't I just turn the lens around and hold it in place. I know, not the world's best solution, and one major missing component is any control over focus or depth of field, but the picture didn't turn out all too bad. I will continue the experiment.
