When first learning to quilt small is better. You can learn alot of different blocks and you can quilt them on your sewing machine.
I have only made a few large bed sized quilts and sent them out for quilting. No storage room for them either.
A friend of mine has an extra bed she uses to stack all her bed sized quilts on but I dont have an extra bed that dosnt get used so cant store them that way.
I much prefer making smaller quilts anyway.
