It's possible to make anything without any tools, but truthfully, the tools are there to cut down on problems, and no one wants problems. To buy one you have to know whether your machine has a high or low shank, though (I think I said that right, someone correct me if I said it wrong, as it's been so long since I thought about it). Anyway, it's job is to keep the material from edging around and shifting, creating bunching. It's possible to do a good job without one depending on your personal skill and attention to the smallest detail in problems, but if you can get one it will remove more of the risk of doing a bunch of work and finding out it really is a 'bunch' and will now need to be taking out or ditched. They are a blessing, and remove a lot of the risk of problems.
