Step one is to get yourself a T-shirt. There are two things to keep in mind, the size of the knit (look at the rows or ridges on your shirt, the bigger the ridges the bigger the knit. Bigger knit makes this easier and faster. The second thing to consider is size. The more 'ripping' you do, the bigger the shirt gets. I started with a small cheap T-shirt with a very small knit.

|Note: The rip will be the size of the string, not the space it came from.|
Next: Keep ripping. This is the time consuming part. Pop in a good movie and go for it. It gets easier as you go, and you'll soon be able to pull the threads apart with your fingers:
