Here is a picture of something I have been working on. It is two circular pieces of plastic with ~50 holes drilled into it. I had to thread a long string of rayon fiber through each hole... 3 times. The above picture resulted in a failure as there was residue from the drilling between the two pieces of plastic.

Here is a picture of the first failure:

As you can see, it is not nearly long enough to fit into the glass cylinder. The third time, however, I ended up getting it right!
