I hand quilt in my lap with a large (width wise) hoop. In fact, I have 2 sizes one is 10 inches and the other 12 inches., the reason being I am short armed so its easier to hold the 10 inch one. The width is a good inch to inch and a 1/4. Its heavy plastic, from JoAnn's and has a groove in one ring and a ridge in the other which helps hold all the layers in place. The quilt can't be too tight or too loose but you need to make sure the back is smooth (without puckers). I always start in the center and work outwards - there is a lot of info on how to get started if you just look for it.
Good Luck!
