I just bought a starter sewing machine and I don't have any idea why there are two spools of thread running at the top and bottom. It seems like the thread running from the top is the only one that's necessary.

You have to have a thread on top and on bottom, so that they can pierce the fabric from both sides and sew the pieces together. If it only came from the top, there would be nothing on the bottom to pull it back up through the fabric and stitch the pieces together.
I don't know what type of machine that you got, but most are similar in how they work, and I think that it is just going to take time for you to learn how to work it. I have been sewing for over 10 yrs and I still run into problems, so don't let it detere you.

Most MODERN machines use 2 spools, (spool and bobbin) to generate what is called a "lockstitch".
This is a stitch that will stay intact and hold the material together, (more or less,) when the thread wears out or breaks somewhere in the seam.
If you use 2 different colors of thread, you will find that the bottom thread is on the top and the top thread is on bottom AFTER sewing!!
There is ALSO a single thread machine which is used mostly on bags of feed, seed, etc. It is called a "chain-stitch".
If you get the right end loose, and pull the thread, ALL the stiches come out, just like unraveling crocheted or knitted sweaters.

The spool at the top goes down and forms a loop as the precisely timed bobbin at the bottom creates a loop which is caught by the first and drawn up, with the fabric in between creating a running stitch along both sides of the fabric binding two or more layers together. If you look very closely it looks more like crochet happening with the thread than what you accomplish with a hand needle.
So, basically, why does it?......because that is how it creates a stitch that binds fabric together.

Because you need the thread on top & the one on bottom is the bobbin one does each side of the material otherwise the sewing wouldn't get done right.

it variety of appears like Kay is conventional with what she's speaking about yet enable me upload something... once you load the bobbin into the case, be particular you've it going the right way. have self belief it or not, it concerns. it isn't difficulty-free to describe in writing, yet once you're protecting the case about to drop the bobbin into it, the bobbin thread must be able of unroll counter-clockwise. I tell myself that the thread must be a backwards "6". at the same time as the thread is slid into the bobbin stress plate section, it ought to sorta be folding decrease back not likely with the bypass. Does that make experience? 9 out of 10 situations in the experience that your gadget in simple terms starts messing up once you install a clean bobbin, it truly is what you probably did incorrect. i have been considered as a genius some situations when I've shown this to acquaintances, yet an expert upholsterer taught me this. I continually wondered what must be blamed for this. i desire it helps! of route, you ought to re-modify your tensions too in case you've were given all of them out of whack now too, yet this can help!
