You can do it by hand without the tool. You just have to make sure you keep the serving tight as you wrap it. You might be able to wrap the serving around a pen once or twice and then wrap the pen around the string to keep it tight. It will not be as good as with the tool but it should get you by for a little bit. You definitely need some way of keeping he serving tight as it's wrapped around the string.
