My hobby is quilting, which involves sewing layers of fabric together to make a material that is padded and thicker. 
How did you learn to do that? I bet they are beautiful.
My mom taught me. I have made bed spreads and various wall hangings over the years. 
How much time does it take for you to make them?
It can take months when I'm doing the quilting by hand. You can also use a sewing machine, which is much faster!
I bet it is very time consuming.  Does it take a special type of sewing machine?
I just have a regular old sewing machine. You can get something called a longarm sewing machine, which is industrial length and much faster.
I've never heard of that kind.  What type of fabric do you use?
Different kinds of cottons for the quilt top, and then I use something called batting for the insulating material.
