I have a few questions about my sewing machine. I figure its about time I learn how to use certain parts now that ive had it for about 5 years or so. ( Got it as a gift when i was ten!)
So There are a bunch of feet that i would love to know what they do. And i want to know how to be able to take the circular thing out to change the shape of the stitch. Well, i took pictures since i dont know what the pieces are called.

thats where it is

I just don't know how to get the black circle out to put one of these in...

and i don't know what ANY of these feet do!

thanks.
